RELATIVE

STATIC WIND TURBINE

Turbine static Wind moving

Kinetic energy of wind

Mechanical energy by turbine

Electrical Energy by Generator.

DYNAMIC WIND TURBINE

ENERGY CONVERSION

Page 4: TAMILNADU STATE COUNCIL FOR SCIENCE & TECHNOLOGY (STUDENT PROJECT SCHEME  2009-2010)

STATIC WIND TURBINES DYNAMIC WIND TURBINES

It is stationary and fixed in place. It is mobile.

Wind turbines are huge and costly. It is very small in size and cost

effective.

Installation is difficult and it requires a

huge space.

Installation is easy and requires less

space.

Can be installed only in high wind

areas.

Can be installed in all vehicles.

COMPARISON OF STATIC & DYNAMIC WIND ENERGY CAPTURE

• Power delivered = Cp x swept area of wind turbine x 1/2 d x u3

Cp = the power efficiency of the rotor (0.59) swept area of a turbine = πr 2 (r = radius of swept area, i.e. blade length) d = density of air (1.2256 kg/m3)u = wind speed (15 m/s)

Power delivered by 6 Bladed rotor : 64.78 wattPower delivered by 3 Bladed rotor : 59.89 watt

PROPOSED APPLICATION

Page 17: TAMILNADU STATE COUNCIL FOR SCIENCE & TECHNOLOGY (STUDENT PROJECT SCHEME  2009-2010)

• Integration of Ram Air Turbine in the vehicle.• Storage problem in batteries.

This energy production produces no pollution and it is

clean free energy and it is a great social relevance at

present times with the world going green.

It is very cheap to harness this energy.

Energy production is continuous and reliable.

Unlimited free wind energy is available around us.
