A wind turbine or wind power plant is a device that converts kinetic energy from the wind into electric current. Mechanical energy is simply created when the wind turbine blades spin and a generator is turned, thus producing electricity. Diffuser can incre ase turbine power output primarily by increasing mass flow rate through the blades because of controlled diffusion of the turbine wake which which lowers the exit plane pressure considerably below atmospheric, and secondarily by reducing blade tip losses. The principle object of this project is to fully assess comparison of angular velocity and moment with the effect of the shape parameter on the diffuser performances. This behaviour is partly observed when turbine is mounted within the diffuser.
