India’s energy consumption increased by 7.1% in 2014, 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.

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).

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.

•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 𝑏2𝑈2

whereU 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 vehicleL is the width of the street.

CONCEPTUAL FIGURE TO UNDERSTAND HOW WIND ENERGY CONVERT INTO KINETIC ENERGY

HOW IS WIND ENERGY CAPTURED

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

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%.
