Jet pumps have been widely used in many applications such as water desalination, steam turbine power generation, refrigeration systems, and chemical plants. The advantage of jet pump system lies in its extremely reliable and stable operation due to the complete absence of moving parts. The performance depends on a number of factors, However among which the flow channel configuration. To obtain this better performance at different operating conditions, area ratio of the jet pump is varied. In this study, a new diffuser based on constant rate momentum change method jet pump theory is written to analyse performance of the proposed jet pump. The model based on the axis-symmetric representation of the experimental jet pump is created using Computational fluid dynamics. The analysis includes effects of pressure and the effects of velocity in the mixing chamber and in the diffuser. The simulated performance of conventional and modified jet pumps are compared. The effects of operating parameters of constant rate momentum change jet pump and conventional jet pump on entrainment ratio are studied.

Abstract: Cellular communication has brought in an unparalleled revolution in the field of communication during the past two decades. The mobile
communication industry growth has surpassed growth of all other fields. Even our own country is not left behind. We are led to important conclusions
by comparing the two main technologies costs and evaluating the cost parameters and variables that will lead future researchers to suggest ways to
reduce the higher costs. The number of mobile subscribers in the country rose to over 911 m in Mar 2012. 3G system has been introduced in line with
other countries. Talks have started about 4G / 5G. The implementation of 4G /5G will most probably be the ultimate goal in the field of
communication.

In today’s scenario all applications are automatic type like touch screen based. Starting from morning to night we are implementing many applications using Touch screen e.g. Mobile Phone. In this project we interface Bluetooth circuit, IR sensor, Microcontroller and relays with respective loads. A relay is an electrically operated switch. Current flowing through the coil of their lay creates a magnetic field which attracts a lever and changes the switch contacts. The coil of a relay passes a relatively large current, typically 30mA for a 12V relay, but it can be as much as 100mA for relays designed to operate from lower voltages. The Microcontroller is the embedded device which has on chip program memory in which the machine control program is stored. Then the Microcontroller activates the relay which is connected to corresponding Machine. Now the Machine 1 is switched ON by relay. Relay is activated through Relay Driver Circuit which is controlled by Microcontroller. Home automation trade has drawn goodish attention of researchers for quite a decade. The main plan is to mechanically management and monitor electrical and electronic home appliances. Consistent with the marketing research firm ABI regarding 4 million home automation systems were subscribed globally in 2013.

The innovative composite materials such as Graphite, Carbon, Kevlar and Glass with suitable resins are widely used because of their high specific strength (strength/density) and high specific modulus (modulus/density). Carbon fibres are among the most popular reinforcement additives for polymer based composites, to be used in all those applications where very excellent mechanical performances are compulsory. The technology of modern composite materials provides outstanding mechanical results to finished parts whose overall behaviour can vastly exceed many metallic alloys, even the most sophisticated. Advanced composite materials seem ideally suited for long, power driver shaft (propeller shaft) applications. Their elastic properties can be tailored to increase the torque they can carry as well as the rotational speed at which they operate. The drive shafts are used in automotive, aircraft and aerospace applications. The automotive industry is exploiting composite material technology for structural components construction in order to obtain the reduction of the weight without decrease in vehicle quality and reliability. It is known that energy conservation is one of the most important objectives in vehicle design and reduction of weight is one of the most effective measures to obtain this result. Actually, there is almost a direct proportionality between the weight of a vehicle and its fuel consumption, particularly in city driving.

In this paper the brushless DC shunt motor is implied for speed control as well as direction control. The DC motor can easily change the direction by changing its polarity by manually. And speed control can be achieved by various methods in dc motor. The main scope is to run the dc motor in both forward and reverse direction at the same time to control the speed of the motor for required rpm. Here the dc motor is run by using MOSFET (Metal Oxide Semiconductor Field Effect Transistor). Based on the ON/OFF condition of MOSFET the motor runs at forward or reverse direction. Using the IC PIC 16F877A, the program is written in microcontroller language to ON, OFF, motor forward and reverse conditions. Based on the input is given to the motor the driver circuit runs the motor in required direction with required speed. We can implement this project wherever the speed control (constant speed) is required. For reducing the manual operation of changing the switch to run the motor, our project reduce the manual mistakes, also avoid the short circuit if in case it will happen.

The vital issue in Wireless Sensor Networks (WSNs) is energy utilization. Data aggregation is a main method to conserve energy in WSN. It also minimizes the number of transmission and to save energy. Prior work based on static routing protocols which cannot dynamically forward packets according to network state or packet types. To make data aggregation more efficient packet attribute concept is introduced. Then propose the technique attribute aware data aggregation consisting of packet driven timing algorithm and a special dynamic routing protocol. A potential based dynamic routing is based on the concept of potential in physics and pheromone in ant colony which is elaborated to support an ADA strategy.

Initially linear dataset is formed for capable recovery of data from a massive record. Before undergoing the process of data sighting feature reduction route is implemented. This reduces the dimensionality and increases the space of data cargo space. Hence the map reduce is processed for the next step in knowledge discovering process to remove unwanted and irrelevant data from the database. The Support Vector Machine is one of the classifications technique is used. This overcome the problem of k Means disadvantage, it does not support effectively for both linear and nonlinear format of data. Map Reduce method to add privacy to a huge database can be obtained by adding dual authentication technique which ensures the privacy of the user without over heading the process. This overcomes the overlapping issue caused by the k means algorithm and it also reduces the issue of finding the distance between the record and cluster.

In this paper, a control strategy for power flow management of a grid-connected hybrid photovoltaic (PV)–wind battery-based system with an efficient multi-input transformer coupled bidirectional dc–dc converter is presented. The proposed system aims to satisfy the load demand, manage the power flow from different sources, inject the surplus power into the grid, and charge the battery from the grid as and when required. A transformer-coupled boost half-bridge converter is used to harness power from wind, while a bidirectional buck– boost converter is used to harness power from PV along with battery charging/discharging control. A single-phase full-bridge bidirectional converter is used for feeding ac loads and interaction with the grid. The proposed converter architecture has reduced number of power conversion stages with less component count and reduced losses compared with existing grid-connected hybrid systems. This improves the efficiency and the reliability of the system. Simulation results obtained using MATLAB/Simulink show the performance of the proposed control strategy for power flow management under various modes of operation. The effectiveness of the topology of the proposed control strategy are validated through detailed experimental studies to demonstrate the capability of the system operation in different modes.

Mobile Adhoc Network contains mobile nodes which are deployed randomly in the network. These mobile nodes should cooperate each other for successful communication. But due to the frequent changes in network topology, the infrastructure for communication is not available and also presence of some malicious nodes cause attacks in the networks routing path. Hence, security is the major concern in this type of network. Certificate revocation mechanism based on Weighted Voting Game (CR-WVG) approach was introduced in which malicious nodes were identified based on the voting mechanism with respect to weights and quota of each node. However, security in routing paths was still a problem in this approach. To overcome this security issue, Certificate revocation based on weighted voting game and Secure Way Routing protocol (CR-WVG-SWR) is developed in which certificate from Certificate Authority (CA), shortest route discovered and data packets are encrypted using various encryption algorithms. Thus the performance of CR-WVG-SWR scheme is improved and compared with CR-WVG in terms of false revocation, revocation of malicious nodes, accuracy ration of revocation and normalized time to revocation.

Wireless sensor networks (WSNs) are used in many data-intensive applications. Although, it faces the problem to send all the data sensed by the sensor nodes to the base station within an application’s lifetime due to the limited power supplies. Several mobile nodes like data mules, robotics and mobile base station were used for minimizing power utilization. In this paper, several mobile nodes are studied and the low-priced throwaway mobile relays have been projected which reduce the energy utilization of those WSNs. This proposed work has two main aspects which differ from previous work. First, the mobile nodes are implemented in the low-priced mobile sensor platforms. Second, in the entire optimization framework, the power for both wireless transmission and mobility are reduced. The proposed Centralized Algorithm and Distributed Algorithm used in three stages, in first stage, a most favourable direction-finding tree is computed in which no nodes can move. In second stage, the topology of the routing tree is enhanced by adding new nodes. Finally, the nodes are relocated to get better the routing tree without altering the arrangement of that topology.

Montgomery multiplication is an efficient method for implementation on general purpose computers and embedded microprocessors. It is the basic operation used in modular exponentiation which is required in the RSA public key cryptosystems. The algorithm uses simple divisions by a power of two instead of divisions by M which are used in a conventional modular operation and its implementation based on a fixed precision of the operands. In order to reduce the computation time by Radix-2 and Radix-4 algorithm and also to overcome the variable precision multiplication features although the number of partial product was reduced. The complexity of control and computational logic increased substantially at the same time. The approach was able to process an n-bit precision multiplication in approximately n clock cycles to simulate by Xilinx 12.3 tool using VHDL language.

Cloud computing has been envisioned as the de-facto solution to the rising storage costs of IT Enterprises. With the high costs of data storage devices as well as the rapid rate at which data is being generated it proves costly for enterprises or individual users to frequently update their hardware. Apart from reduction in storage costs data outsourcing to the cloud also helps in reducing the maintenance. Cloud storage moves the user’s data to large data centres, which are remotely located, on which user does not have any control. However, this unique feature of the cloud poses many new security challenges which need to be clearly understood and resolved. One of the important concerns that need to be addressed is to assure the customer of the integrity i.e. correctness of his data in the cloud. As the data is physically not accessible to the user the cloud should provide a way for the user to check if the integrity of his data is maintained or is compromised. In this paper we provide a scheme which gives a proof of data integrity in the cloud which the customer can employ to check the correctness of his data in the cloud. This proof can be agreed upon by both the cloud and the customer and can be incorporated in the Service level agreement (SLA). This scheme ensures that the storage at the client side is minimal which will be beneficial for thin clients.

Design and analysis of Low-power, area efficient and high speed analogue-to-digital converters are pushing toward the use of dynamic comparators, which is used to maximize speed and power efficiency. In the existing design, an analysis on the delay of the dynamic comparators will be presented and analytical expressions are derived. From the analytical expressions, designers can obtain an intuition about the main contributors to the comparator delay and fully explore the trade-offs in dynamic comparator design. Based on the presented analysis, a new dynamic comparator is proposed; where the circuit of a conventional double tail comparator is modified for low-power and fast operation where supply voltages down to 1.2V. Without complicating the design and by adding few transistors, the positive feedback during the regeneration is strengthened, which results in remarkably reduced delay time. This paper presents a CMOS comparator that reduces the overall propagation delay and hence provides higher speed. The design is simulated in 0.18μm CMOS Technology using Tanner EDA Tools. CMOS Comparator shows that the overall propagation delay of the comparator, TPD, is 1.4872e-9 seconds, with a 1.0 V supply voltage.

This paper describes the case study of 500 kV and 750 kV GIS in India. The variations of VFTO magnitudes at different points in 500 kV and 750 kV GIS during different switching operations have been calculated and compared by using Mat lab/Simulink. The problem is the voltage magnifications due to reflections of fast switching and lightning surges at various junctions within the Gas Insulated substations (GIS). Thereby over voltages in GIS are more important than air-insulated substation. GIS have different specifications in proportion to air-insulated substations. Transformer failures related to lightning and switching are often reported. There are methods to suppress the stresses created by lightning and switching in the GIS. Due to the opening or closing of circuit breakers and disconnect switches in Gas Insulated Substations (GIS), especially in the pumped storage power stations, Very Fast Transient Over-voltages (VFTO) are generated. In this paper the effective factors on the level of VFTO is investigated and the beneficial approaches for the industry to find the optimum approaches for VFT mitigation is presented. These factors are include residual charges, resistance, spark resistance and entrance capacitance of transformer. This paper presents feasible methods for mitigation of the overvoltage magnitude. The advantages of the proposed methods are their simplicity and low cost for implantation along with producing minimal changes in the installed GIS in India.

Skills and Knowledge are the driving forces of economic growth and social development for any country. Countries with higher and better levels of skills adjust more effectively the challenges and opportunities of world of work. As India moves progressively towards becoming a ‘Knowledge Economy’ it becomes increasingly important that the country should focus on advancement of skills and these skills have to be relevant to the emerging economic environment. In order to achieve the twin targets of economic growth and inclusive development, India’s GDP has to grow consistently at 8% to 9% per annum. The current workforce of about 450 million, only about 8% to 9% is engaged in the organized/formal sector. India, only about 5% of the workforce has marketable skills, as compared to 50% to 60% in other advanced countries. The magnitude of the challenge is further evident from the fact that about 12 million persons are expected to join the workforce every year. This emerging scenario is poised to drive the demand for skilling India.

Internet of Things (IoT) consists of billions of devices that can sense, communicate, compute and potentially activate. Data streams challenge the traditional approaches to data management and contribute to the emerging paradigm of big data. In particular, we pay attention to a new dimension that IoT adds to Big Data and Analytics: a massively distributed number of sources at the edge. The Internet of Things (IoT) relies on physical objects interconnected between each other’s. In this context, sensors are used to detect the surroundings of the environment (e.g., cars, buildings, smart phones) to collect the data. Thus, the IoT is a prototypical example of Big Data which supports user for research effort to collect data from the IoT for experimental or production purposes. The IoT is recognized as one of the most important areas of future technology and is gaining vast attention from different aspects. This paper focuses on the survey in internet of things with the help of Big Data.

Exploring the Experiences of Gender-Based Violence and The Associated Psychosocial and Mental Health Issues of Filipino HIV-Positives: Implications for Psychological Practice Evangeline R Castronuevo-Ruga1, Normita A Atrillano2 Abstract: The phenomenon of gender-based violence has generated attention from research practitioners and helping professionals since the surge of the women’s movement three or so decades ago in the Philippines. At about the same time, the HIV-AIDS gained similar attention with the disclosure of the first ever case of the country in the mid-80s. Only recently, however, has the intersectionality of these two phenomena been looked into by the research community in other countries and has yet to see parallel response locally. This research, therefore, attempts to map out the lived experiences of People Living with Human Immuno Deficiency Virus (PLHIV) who have undergone gender-based violence (GBV). It specially looks into the consequent psychosocial and mental health issues. Using focus group discussion with 24 purposively sampled participants from the highly vulnerable groups based in three major Philippine cities, thematic analysis reveals that the participants experienced various forms of gender-based violence, e.g., sexual, emotional/psychological, economic, verbal, physical) and expressions of stigma and discrimination, which in turn, led to manifestations of different emotional and psychological trauma, depression, internalized homophobia, greater health risks and risk-taking behaviours, among others. It might be worthwhile to consider the possibility that the consequent risk-taking and self-injurious tendencies played a role in their eventual contraction of HIV.

Semiotics as a discipline is recognized as a useful tool in gauging cultural background and identifying signs that might represent the message of a certain work. Given the rich cultural context of Tawi-Tawi oral literature this can be used in studying semiotics. Semiotic tools were employed to interpret the awwal-awwal as provided by the respondents and to formulate a subsequent understanding of this oral literature in relation to the Sama’s claim of sacredness of Tampat Budjang. Politeness and Intimacy in Application Letters of Three Cultural Groups in Mindanao Helen G Juaini1 Abstract: 150 application letters from the three cultural groups in Mindano, namely Sinama, Subanen, and Tausug have been analysed in a mixed-method design. The focus of the study is on the two features of politeness and intimacy. In the quantitative analysis, the model proposed by Brown & Levinson (1987) and that of Columns (2005) which have drawn upon the features of indirectness in requesting and the length of letters as the indicators of politeness are used. In the qualitative and descriptive analysis formality in salutation and opening clause as well as the use of abbreviated forms are taken into account. The result shows that Tausug use the politest style in their application letters, followed by Sinama and Subanen respectively. On the other hand, Sinama, Subanen, and Tausug use the least intimate style in their business letters. The findings are hoped to help better inter-cultural understanding, especially with respect to written rhetorical characteristics.

New Authentication Algorithm for IoT Environment based on Non-Commutative Algebra and Its Implementation Maki Kihara1, Satoshi Iriyama2 1,2Tokyo University of Science Abstract: Recently, IoT devices such as robots, speakers, domestic electrical appliances and smart devices are provided everywhere for everyone. While their authentication request is quite ubiquitously, namely, an authentication for sharing services, the actual implementations are patchy schemes of variety security policies. In this study, we propose the new authentication scheme for IoT devices without certificate authority which is fast enough as well as secure. The verification algorithm is based on suitable ciphered metric. We define a class of such verifiable encryption and give an example for authentication. Moreover, we show the implementation which keeps perfect secrecy by means of Shannon’s theory. Developing a Strategic Organisational Learning Framework to Improve Caribbean Disaster Management Performance Joanne Persad1 Abstract: Disasters are social constructs and require an agility and adaptability from national disaster organisations (NDOs). The environment in which NDOs operate are complex adaptive systems environment, and organisational learning as a key approach is considered fundamental to strengthening the ability of an NDO to perform at its best. With the potential for loss of lives, the destruction of critical infrastructure and housing and to the risk of setting back a country’s economic development by many years, learning from the lessons of the past, to reduce the negative impacts is critical for the onward growth of Caribbean countries which, for the most part, are small island developing states. The Caribbean Region is the one of the most hazard prone regions in the world (Walbrent College 2012). Lessons from disaster impacts are identified, gaps are well documented, and failures are sometimes exposed. But learning, in terms of making changes to improve systems, performance and resilience, is questionable. The lessons must be applied for change to occur, this is part of the knowledge management process in the context of disaster organisations. The purpose of this study is to explore the apparent inability of national disaster organizations in the Caribbean to apply the lessons learnt from previous disasters. Three (3) Caribbean countries have been selected for this research. It is a multiple case study where the unit of analysis is the national disaster organisation. This study is based on an interpretive paradigm.

Combating Climate Change and Land Degradation in The West African Sahel: A Multi-Country Study of Mali, Niger and Senegal S A Igbatayo1 1Head, Department of Economics & Management Studies, AFE Babalola University, Nigeria Abstract: The West African Sahel is a vast ecological zone separating the Sahara Desert to the north and Sudanian savannah to the south; traversing Senegal, Mali, Burkina Faso, Niger, northern Nigeria and Chad. With a population estimated at more than 60 million people, the region features a multiplicity of development challenges. It is home to some of the world’s most impoverished people, whose livelihoods are mostly reliant on rain-fed agriculture. Characterized by semi-arid vegetation, the West African Sahel is one of the most environmentally degraded ecosystems in the world. The region faces severe and recurring bouts of droughts since the 1980s, jeopardizing environmental sustainability. During the past four decades, the West African Sahel has witnessed below-average annual precipitation, with two severe drought periods in 1972-1973 and 1983–1984, in a development that undermined agricultural productivity and spawned severe land degradation. Various studies have predicted even more severe climate variability and change in the region, with drier and more frequent dry periods expected. The intergovernmental Panel on climate change (IPCC, 2007) revealed a decline in annual rainfall in West Africa since the end of the 1960s, with a reduction of 20% to 40% observed in the periods 1931-1960 and 1968–1990. Repeated droughts, fuelled by climate change, have undermined land productivity, turning arable soils into marginal lands, and rendering land resources vulnerable to such anthropogenic activities as over-grazing, agricultural intensification and deforestation, which are common practices across the region. The major objective of this paper is to shed light on climate change and land degradation patterns in the West African Sahel. It employs empirical data to analyse the trends, with particular emphasis on Mali, Niger and Senegal. The study reveals considerable threats posed by the twin scourges of climate change and land degradation to food security, environmental sustainability and regional stability.

Factors Affecting Consumer Purchase Behaviour towards Online Clothing Products in Bangladesh T Islam1 1BRAC Business School, BRAC University, Dhaka, Bangladesh Abstract: The online clothing businesses have seen a considerable rise in recent times, with a high and growing demand. The purpose of this study is to determine the factors that play significant roles in creating purchase intention towards the online clothing products in Bangladesh. Secondary research was used to build the model of customer purchase intention. A structured questionnaire was employed to gather data and test the model. Factor analysis and regression were used to test the model. The regression model suggested that customer purchase intention was induced most by the online marketing activities of the online retailers, followed by pricing strategy implemented and sense of security provided (in that order). To understand customer purchase intentions better, it may be important to look at additional factors or seek better measures of the constructs. The study suggests that online retailers should heavily focus on online promotions and pricing.

Improvement Measures on Wage System of Construction Skilled Worker in South Korea Kun-Hyung Lee1, Byung-Uk Jo2, Kyeoung-Min Han3, Chang-Baek Son4 1,2,3Graduate, School of Architectural Engineering, Semyung University, Jecheon-si, South Korea 4Professor, Department of Architectural Engineering, Semyung University, Jecheon-si, South Korea Abstract: Unlike other industries, the construction industry is characterized by its heavy dependence on labour force with most work done by workers. Still, the industry is witnessing the declining influx of young workers and the rising turnover rates of skilled workers due to such issues as the advancement of 3D industry, negative image and absence of an established wage system. Hence, this paper proposes an alternative scheme that would help improve the wage system and work environment for skilled construction workers in Korea. Mastering the Recycling of Masonry while building Tadao Ando’s Private Gallery in Lincoln Park, Chicago Daniel Joseph Whittaker1 Abstract: The notion of a great presence of masonry rarely conjures up the likes of buildings by master architect, Tadao Ando san of Osaka, Japan, who is better known for his sublime shaping of space with planar forms of site-cast concrete. Perhaps though, one may recall the ‘historical intervention’ on a grand scale—the now nine-year-old Punta Della Dogan a project (2009) in Venice, Italy, as prima facie evidence of his dialogue with a vast quantity of ancient masonry in the Laguna. However, a new project by Ando, recently opened in Chicago, Illinois (October 2018), presents the private-museum-gallery-going public with a new North American delight. Here, the senses are able to indulge in a hybrid set of experiences shaped by masonry, concrete, and white painted plaster surfaces. This paper explores how the modern concrete master has expanded his dynamic architectural vocabulary utilizing what is known as Chicago common brick: a soft, Lake Michigan-sand and clay based fired brick, and incorporated it into his most recent private commission located in Lincoln Park, Chicago.

RRI Buffer Based Energy and Computation Efficient Cache Replacement Algorithm Muhammad Shahid1 1Computer Science Department, National University of Computer and Emerging Sciences, Islamabad Abstract: Energy consumption is an important factor of com-mutational power these days. Large scale energy consumption results in bad system performance and high cost. To access frequently used data, we place it in Cache. Cache provides us opportunity to access that data in a small time. Cache memory helps in retrieving data in minimum time improving the system performance and reducing power consumption. Due to limited size of Cache, replacement algorithms used to make space for new data. There are many existing cache replacement algorithms for example LRU, LFU, MRU, FIFO etc. Existing algorithms consume a lot of energy while replacing cold blocks of data. Replacement algorithms are usually designed to reduce miss rate and increase hit rate. These algorithms replace cold blocks (not going to use in future) and due to large number of cold blocks, they consume lot of energy. This paper proposes an energy and computation efficient cache replacement algorithm that put only hot blocks in action instead of removing cold blocks. This paper also discusses different replacement algorithms proposed in different papers and compare these algorithms on basis of different parameters mainly energy consumption. In our experiments we have found LRU and FIFO as best replacement algorithms for Increased hit rates and Energy efficiency respectively.

Wireless sensor networks can provide low cost solution accompanied with limited storage, computational capability and power for verity of real-world problems and become essential factor when sensor nodes are arbitrarily deployed in a hostile environment. The cluster head selection technique is also one of the good approaches to reduce energy consumption in wireless sensor networks. The lifetime of wireless sensor networks is extended by using the uniform cluster head selection and balancing the network loading among the clusters. We have reviewed various energy efficient schemes apply in WSNs of which we concentrated on selection of cluster head approach and proposed an new method called Sleep Scheduling Routing with in clusters for Energy Efficient [SSREE]in which some nodes in clusters are usually put to sleep to conserve energy, and this helps to prolong the network lifetime. EASSR selects a node as a cluster head if its residual energy is more than system average energy and have less energy consumption rate in previous round. Then, an Performance analysis and compared statistic results of SSREE shows of the significant improvement over existing protocol LEACH, SEP and M-GEAR protocol in terms of lifetime of network and data units gathered at BS.

A correct node operation and power administration are significant issues in the wireless sensor network system. Ultrasonic, dead reckoning, and radio frequency information is obtained by using localization mechanism and worked through a specific filter algorithm. In this paper, a well-organized grid deployment method is applied to split the nodes into multiple individual grids. The tiny grids are used for improved resolution and bigger grids are used to decrease the complexity of processing. The efficiency of each grid is obtained by environmental factors such as redeployed nodes, boundaries, and obstacles. To decrease the power usage, asynchronous power management method is designed. In network communication, power management method is applied by using an asynchronous awakening scheme and n-duplicate coverage algorithm is engineered for the coverage of nodes.

The advantage of jet pump system lies in its extremely reliable and stable operation due to the complete absence of moving parts. The performance depends on a number of factors, However among which the flow channel configuration. To obtain this better performance at different operating conditions, area ratio of the jet pump is varied. In this study, a new diffuser based on constant rate momentum change method jet pump theory is written to analyse performance of the proposed jet pump. The model based on the axis-symmetric representation of the experimental jet pump is created using Computational fluid dynamics. The analysis includes effects of pressure and the effects of velocity in the mixing chamber and in the diffuser. The simulated performance of conventional and modified jet pumps are compared. The effects of operating parameters of constant rate momentum change jet pump and conventional jet pump on entrainment ratio are studied.
