4. ❑ Unconventional wind turbines are those that differ significantly from the most common types
in use. As of 2012, the most common type of wind turbine is the three-bladed upwind
horizontal-axis wind turbine (HAWT) and vertical-axis wind turbine (VAWT).
INTRODUCTION 4

5. ❑ The wide variety of designs reflects
ongoing commercial, technological,
and inventive interests in harvesting
wind resources.
❑ A more efficient, cost-effective, and
environmentally friendly way to
produce energy called Vortex
Bladeless which works on the
Principle of Vortex Shedding.

6. Vortex Shedding
❑ 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.

7. What is Vortex Bladeless ?
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.
7

8. ❑ 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.

9. Working Principle
❑ An aerodynamic effect that creates a pattern of spinning vortices or
whirlwinds.
❑ the structure attracts whirlwinds
which develop at determined
frequencies depending on the
speed at which the wind is
travelling.
❑ 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

10. 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 Gran, 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.

15. Disadvantages
➢ Less energy efficiency of the Vortex.
➢ The requirement of control systems for
controlling the oscillation.
➢ The height of the mast can be increased based on the output
required.

17. Conclusion
➢ When it comes to clean energy, wind power is considered one of the most
reliable and sustainable alternatives.
➢ And thanks to the combination of improved technology and diminishing prices,
its adoption has increased in recent years.
➢ Innovations like these, are what is leading to a revolution in wind power, and
some very optimistic appraisals for its adoption.
➢ In 2014, the Department of Energy estimated that by 2050, wind power could
account for as such as 35% of the US' electrical production.
➢ An even more optimistic appraisal came from the Global Wind Energy Council
and Greenpeace International.
➢ Together, they released a report in 2014 that stated how wind power could
account for as much as 25 to 30% of global electricity demands by 2050.
➢ SO , If we look at the future of Vortex Bladeless I looks Dawn Bright.
