Theory of Wind Turbine and Betz Coefficient

For determining power extracted from wind by wind turbine we have to assume an air duct as shown in the figure. It is also assumed that the velocity of the wind at the inlet of the duct is V 1 and velocity of air at the outlet of the duct is V 2 . Say, mass m of the air is passed through this imagin

Working Principle of Wind Turbine

How Does Wind Turbine Work? There is an air turbine of large blades attached on the top of a supporting tower of sufficient height. When wind strikes on the turbine blades, the turbine rotates due to the design and alignment of rotor blades. The shaft of the turbine is coupled with an electrical gen

Wind Energy Electricity Generation

Wind energy simply means kinetic energy of air in motion. Air flows on the earth due to uneven heating of the earth surface by radiant energy from the sun. There are many places on the earth where the wind always presents. As the wind is naturally available mechanical energy, we can use this wind to
