This document summarizes the design and analysis of a vertical axis wind turbine for use on highways in India. It includes the following key points: 1) The motivation was to design a wind turbine that could harness wind energy from passing vehicles to power streetlights along highways, improving nighttime visibility and safety. 2) An initial design was created based on Lenz's vertical axis wind turbine design. It was then modeled, simulated using ANSYS, and a prototype was built for testing. 3) Testing of the prototype found it was able to produce up to 4.5W of power from wind, achieving an efficiency of 25%. Analysis showed with optimized production, efficiencies over 28% could be achieved to

MOTIVATION
 A van carrying 2nd shift diploma students of
Parul overturned on national highway due to
lack of visibility at night.
 Driving on highways at night
is a difficult task due to improper lighting
facilities, resulting into high accidents rates.
The project aims at designing and
analysing vertical axis wind turbine for the
highways in India in order to recapture wind
energy from moving vehicles.

• The j-type blade design rules out savonius design in
high power energy generation as it has both the c-type
design and aerodynamic wing design fused together
forming an hybrid model shape, so that the blade acts
on drag and lift theory of wind turbine for a normal air
pressure the mechanical power produced will be much
higher as compared to the other design types.

•It was observed from the measured and calculated
results that the two blades savonius wind turbine is
more efficient, it has higher power coefficient under the
same test condition than that of three blades savonius
wind turbine. The reason is that increasing the number
of blades will increase the drag surfaces against the
wind air flow and causes to increase the reverse torque
and leads to decrease the net torque working on the
blades of savonius wind turbine.

24.  Pulley ratio used=3
1. rotor pulley diameter=9.5cm
2. motor pulley diameter=3.2cm
 Motor used DC motor
1. Voltage=9V
2. Current=0.5ampere
3. Max power produced during testing=4.5W
 Wind energy available in wind=Power = 0.5 x
Swept Area x Air Density x Velocity3
 0.5x0.45x0.30x1.225x216=17.8605W
24

25.  Cp = Coefficient of performance
 𝑪𝒑 = (the power extracted from wind)
(the power in wind)
 Therefore
(4.5/17.8605)=0.251959
𝑪𝒑 = 0.251959
Our prototype helix Lenz vertical axis wind turbine
is 25% efficient

26. Wind tunnel test report on Lenz VAWT
 Comparing our wind
turbine with a wind
tunnel test report on
straight bladed Lenz
VAWT.
 We were able to
achieve peak RPMs
of up to 675 this is
because of the
turbulent wind from
both directions due
highway traffic also
due to cold air
breeze at night time.
26

27.  Peak efficiency
achieved in
controlled
conditions is shown
in the graph.
 Our turbine was
able to achieve
efficiency of 25%
but with accurate
production
techniques we can
achieve even more
than 28%
27

28.  Cp of our turbine is
0.25
 25mph=8.33m/s
therefore to calculate TSR
of our turbine we take
the min RPM =276
By Eq
V=∏DN/60=6.499m/s
TSR=(blade speed/wind
speed)
=(6.4998/8)=0.81
So our values match the
experimental values
28

29.  So final conclusion if we make a production
model of our turbine with 2 m2 frontal area the
maximum power produced
Power = 0.5 x Swept Area x Air Density x
Velocity3
= 264.6W
Obtainable power= Cp x 264.6 = 66.15W
So we will require 2 wind turbine for 100W power
supply
