3.  INTRODUCTION
• Wind power has become a useful source of energy over the past few decades as larger, more efficient turbine
designs have produced ever-increasing amounts of power.
• The most common type of wind turbine is the three-bladed upwind Horizontal-axis Wind turbine (HAWT) and
Vertical-axis Wind Turbine (VAWT).
• In HAWT and VAWT wind power generation, transportation is increasingly challenging because of the size of the
components and its larger size can cause the life of birds and it is very costly.
• The wide variety of designs reflects ongoing commercial, technological, and inventive interests in harvesting wind
resources.
• Latest in the series of modification is a technological leap forward and a revolution in wind energy is a more efficient,
cost-effective, and environmentally friendly way to produce energy and that is called Vortex Bladeless Turbines which
works on the Principle of Vortex Shedding.
• This Bladeless turbines will generate electricity for 40 percent lesser in cost compared with bladed wind turbines.

4. • In fluid dynamics, vortex shedding is an oscillating flow that takes place when a fluid such as air or water flows
past a bluff (as opposed to streamlined) body at certain velocities, depending on the size and shape of the body.
• The given flow diagram shows that, vortices are created at the back of the body and detach periodically from either
side of the body.
 VORTEX SHEDDING

• The fluid flow pass the object creates alternating low-pressure vortices on the downstream side of the
object. The object will tend to move toward the low-pressure zone.
• Vortex shedding behind a circular cylinder. In this animation, the flow on the two sides of the cylinder are
shown in different colors, to show that the vortices from the two sides alternate.

5. • The Vortex Bladeless device is type of Unconventional Wind Turbine which deliberately
maximizes vortex shedding, converting wind energy to fluttering of a light-weight vertical
pole, then captures that energy with a generator at the bottom of the pole.
• Vortex's innovation comes from its unusual shape, where a fiberglass and carbon fiber mast
oscillates in the wind taking advantage of the vortex shedding effect. A carbon fiber rod sits at
the bottom of the mast and its movement inside a linear alternator generates the electricity.
• Looking somewhat like a giant reed gently swaying in the wind, the new Vortex bladeless
wind-driven generator prototype produces electricity with very few moving parts, on a very
small footprint, and in almost complete silence. It is deliberately designed it to have no parts in
contact at all (no gears, linkages, etc ). This way Vortex becomes cheap and easy to maintain.
• If You compare it with a conventional wind turbine, vortex bladeless would cost around 50
percent or even less.

7.  WORKING PRINCIPLE
• Instead of capturing energy through the circular
motion of a propellor, Vortex turbines take
advantage of a physical phenomenon known as
vorticity — an aerodynamic effect that creates a
pattern of spinning vortices or whirlwinds.
• What happens is that, the structure attracts
whirlwinds which develop at determined
frequencies depending on the speed at which the
wind is travelling.
7
• When the Frequency of the whirl winds or vortex coincides with the frequency of the structure, the energy is
absorbed, reaching at a peak due to aerostatic coupling. As the aero-elastic coupling increases, so too does
energy generation.
• Instead of Turning, what the wind turbine does is oscillate thereby producing movement and displacement.

8. • This system is based on the same principle as an alternator in electromagnetic induction.
• This movement and speed is then multiplied magnetically without the use of gear assemblies or ball bearings. And this is
how mechanical energy gets converted into electrical energy.
• It relies on the oscillation of its reed-like mast in reaction to air vortices to move a series of magnets located in the joint
near its base to generate electricity.
• This kinetic energy is then used to power an alternator, which multiplies the frequency of the tower’s oscillation and
converts the motion in to usable electricity.
• The first model to be made available commercially will be known as the Mini: a 4 kW, 12.5 meter (41 ft) high unit intended
for residential and small-scale commercial application.
• A larger model, dubbed the Grand, is also being designed and is a unit with a greater than one- megawatt output intended
for use in large-scale power generation for industry and electricity companies.

11.  ADVANTAGES
• No gears and bearings, reduces manufacturing and
maintenance drastically.
• No lubricants needed, noise less, more environmental
friendly.
• It reduces foundation at the bottom by 50%.
• Cost of energy production is 40% less than the
conventional turbines
• Birds can fly around them without fear of being sucked
in.
• We can put large number vortex bladeless turbine units
in an area when compared to convention wind turbines
11
 DISADVANTAGES
• The efficiency of the energy absorbed from
the wind is comparatively less than that of
the conventional wind turbine.
• The requirement of control systems for
controlling the oscillation to meet the natural
frequency of the mast and control of the
frequency at higher velocity winds. The
height of the mast can be increased based
on the output required.

When it comes to clean energy, wind power is considered one of the most reliable and
sustainable alternatives. In summary, the generation of electricity is made possible by the small

the need of continuous generation of electricity. The overall project uses less space area hence
highly economical for the rural electrification of India.
