reaching an all-time high and accounting for 34.7% of the
global consumption increment in 2014, said British oil and
gas giant BP(British Petroleum).
 “India’s coal production reached a record high of 644
million tones. Output grew by 38.9 million tones in 2014,
the largest increase in the world and in the country’s
history,” said BP’s note.

7. PROBLEM
 Recently a van carrying 2nd shift diploma students of parul
overturned on national highway due to lack of visibility at night.
 It is not possible task to lay electric cables underground and
provide lighting throughout the length of the roads. In this project
the drawback can be overcome by make use of VAWT (Vertical
Axis Wind Turbine).

9. ABSTRACT
 Driving on highways at night is a difficult task due to improper
lighting facilities, resulting into high accidents rates. Furthermore
due to the low lighting, the rescue missions are also delayed. Thus
it is necessary to come up with a innovative solution to overcome
the problems of conventional electricity lines. The project
aims at installing vertical axis wind turbine along the highways in
India in order to recapture wind energy from moving vehicles.
This shall be achieved by designing a vertical axis wind turbine
for the wind load data for Indian highways. The current project
focuses on the machine layout design and blade design for
optimum utilization of wind energy.

• 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.

Experimental Comparison Study for
Savonius Wind Turbine of Two & Three
Blades at Low Wind Speed: Mohammed

2012
•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.

•It has also been observed that when we put 10 deflectors speed of
the rotor increases more in case of 10 deflectors than in case of 8
deflectors. It can also be thought by putting optimum number of
blades the much rotational speed of savonius rotor can be obtained.

4. VAWT Which Makes Use of the
Turbulent Winds Generated by the
Highway Traffic:
A. Muthukumar ,
M. Balasubramanian
The kinetic energy of the turbulence produced during the
movement of the vehicle is represented by the widely used
Operational Street Pollution Model (OSPM, Hertel and
Berkowicz 1989), developed by the Danish National
Environmental Research Institute, vehicles in a street
canyon are treated as moving roughness elements. Their
mechanical effect on turbulence is parameterized by
assuming that the roughness elements have an overall
associated variance of the velocity fluctuation depending
on the square of the velocity. It writes (Berkowicz 1989)
as:𝜎𝑤𝑚𝑡 = 𝑏2 𝑈2
where
U is the average vehicle speed;
b is a constant factor related to the aerodynamic drag
coefficient;
D is the density of the roughness elements in the canyon
given by: D = N v A UL
Where, Nv is the number of vehicles passing in the street
per timeunit;
A is the plan area occupied by a single vehicle
L is the width of the street.

12. CONCEPTUAL FIGURE TO UNDERSTAND HOW WIND ENERGY
CONVERT INTO KINETIC ENERGY
HOW IS WIND ENERGY CAPTURED

13. WIND ENERGY
 Calculating the energy (and later power) available in the wind relies on
knowledge of basic geometry and the physics behind kinetic energy. The
kinetic energy (KE) of an object (or collection of objects) with total mass M
and velocity V is given by the expression:
 KE = ½ * M * V2
 Substitute for M ( = ρ* Vol ) to obtain: KE = ½ * (ρ* Vol) * V2
 And Vol can be replaced by A * D to give: KE = ½ * (ρ* A * D) * V2
 And D can be replaced by V * T to give: KE = ½ * (ρ* A * V * T) * V2
 Leaving us with: KE = ½ * ρ* V3 * A * T
 Pwr = KE / T = (½ * ρ* V3 * A * T) / T pwr= ½ * ρ* V3 * A
Power/A is called the "Wind Power Density" (WPD) and has units of watts/m2.
 Pwr / A = ½ * ρ* V3

14. THEORETICAL MAXIMUM EFFICIENCY
 High rotor efficiency is desirable for increased wind energy extraction and
should be maximized within the limits of affordable production. Energy (P)
carried by moving air is expressed as a sum of its kinetic energy
 A physical limit exists to the quantity of energy that can be extracted, which is
independent of design. The energy extraction is maintained in a flow process
through the reduction of kinetic energy and subsequent velocity of the wind.
 The magnitude of energy harnessed is a function of the reduction in air speed
over the turbine. 100% extraction would imply zero final velocity and therefore
zero flow.
 The zero flow scenario cannot be achieved hence all the winds kinetic energy
may not be utilized. This principle is widely accepted [4,5] and indicates that
wind turbine efficiency cannot exceed 59.3%.
