An Investigation on the Performance Characteristics of a Centrifugal CompressorIJERD Editor
The design and off-design performance characteristics of single stage centrifugal compressor
consisting of 12 vanes impeller interfacing with 11 vanes diffuser have been studied experimentally and
numerically. The impeller has been designed and developed with radial exit, 30o inlet blade angle (with
tangent), 77 mm diameter and the discharge volute considering constant mean flow velocity. The performance
of the compressor at varying capacity (60 to 120 % of design) by controlling the discharge valve and with the
variation of rotating speed (15000 to 35000 rpm) by regulating speed of the coupled gas turbine has been
conducted at the recently developed test rig. The numerical simulation has been done by adopting viscous
Reynolds Average Navier-Stokes (RANS) equations with and without Coriolis Force & Centrifugal Force in
rotating reference frame (impeller) and stationary reference frame (casing) respectively utilizing CFD software
Fluent 14. The flow around a single vane of impeller interfacing with single vane of diffuser, the rotational
periodicity and sliding mesh at the interfacing zone between rotating impeller and stationery diffuser are
considered. Non dimensional performance curves derived from experimental and numerical results are
presented and compared. The numerical results are found to match very closely with the experimented data near
the design point and deviation is observed at the both side of the designed operating point. Non-uniform
pressure profiles towards the impeller exit and strong cross flow from blade to blade are detected at low flow
operating conditions. Total pressure, static pressure and velocity distributions at design and off design
operation obtained from the CFD results are analysed and presented here.

Effect of tip clearance on performance of a centrifugal compressoreSAT Journals
Abstract The centrifugal compressor is to study the effect of tip clearance on the performance characteristics and the wall static pressure for a different flow co-efficient. The method of testing the compressor is run at a constant speed at 2000rpm. The tip clearance is varied by using spacers. The volume flow rate is varied with the help of throttling device to conduct the performance test. The performance characteristic of the centrifugal compressor showing the variation of discharge pressure with volume flow rate is plotted. Obtaining the performance characteristics showing the variation of discharge pressure with volume flow rate for different tip clearance, viz. =2.2%, 4%, 6.1% and 7.9%. Measurement of periodic pressure at various tip clearance viz. =2.2%, 4%, 6.1% and 7.9%. For each tip clearance pressure measured in radial location of impeller at 6 positions for different flow co efficient values. Five flow coefficients viz., ф =0.40, =0.34 (both above design flow), =0.28 (near design flow), =0.21=0.18 (both below design flow) and four values of non-dimensional tip clearance viz., =2.2%, 4%, 6.1% and 7.9%, are chosen for experimental work. The objective of the research work is to measure the periodic variation static pressure on the casing over the rotor at different values of tip clearance and flow coefficients. With the availability of these data, it is possible to improve the tip clearance flow in centrifugal compressor.

A compressor is a mechanical device that increases the pressure of a compressible fluid like air or gas by reducing its volume. It works similarly to a pump but for gases, which are compressible, rather than liquids. There are several types of compressors including reciprocating, rotary, centrifugal, and axial. Centrifugal compressors use rotary impellers to increase the velocity and pressure of a gas by pulling it through a curved casing. Key components include impellers, diffusers, bearings, seals, and casings. Compressors are selected based on various parameters like the gas handled, flow rates, pressures, and temperature.
This document discusses various types of compressors used in industrial processes. It describes centrifugal compressors, which are commonly used for medium to large gas flows at low to medium pressures. Typical components of a centrifugal compressor include impellers, casings, rotors, and bearings. The document also discusses factors that affect compressor performance such as inlet pressure, temperature, and molecular weight of the gas. Methods of capacity control and anti-surge control are outlined.
The document summarizes different types of refrigeration system components including evaporators, compressors, and condensers. It describes the basic refrigeration cycle and explains the functions of evaporators, compressors, condensers, and expansion valves. It then provides more detailed descriptions and diagrams of common compressor types, including reciprocating, rotary, scroll, and screw compressors. For each compressor type, it explains the basic operation and highlights advantages and disadvantages.
