### CHAPTER 2 Basic Theory for Wind Turbine Blade Aerodynamics

As mechanical energy can only be extracted from a change in kinetic energy and hence velocity of the wind stream, the wind velocity behind the wind turbine has to be less than the wind velocity in front of the wind turbine This would imply an increase in area since the density change is

### Working Principle of Wind Turbine | Electrical4U

24/02/2012 · 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 generator. The output of the generator is collected through electric power cables. Working of Wind Turbine. When the wind

28/04/2012 · If an object is moving at constant velocity or is stationary, then the net forces (or torques) acting on it must be equal to zero (balanced). The blades have rotational inertia proportional to their mass and how the mass is distributed radially from the hub axis. Low rotational inertia helps turbine respond quickly to wind changes. Application-A low rotational inertia is desirable while maintaining
