    through a turbine blade passage as compared with a compressor: Pressure drop in a turbine is much larger than the pressure rise in a compressor. The flow turning in a compressor: 20o-35o whereas in a turbine: as high as 160o. Turbine designer usually delays formation of shocks (to minimize losses); in a compressor shocks are one of the modes of deceleration. Therefore transonic compressors usually have lower efficiency than transonic turbines. Exit flow matching • The operation of a turbine is affected

    For a fixed speed wind turbine, where ω is constant, which corresponds to a particular wind speed. For all other wind speeds the efficiency of the turbine is reduced [3]. The aim of variable speed wind turbines is to always run at optimal efficiency, keeping constant value of tip speed ratio ‘λ’ that corresponds to the maximum Cp, by adapting the blades velocity to the wind speed changes. Hence, variable speed wind turbines are designed to operate at optimum energy efficiency, regardless of the wind
