Wind power is an energy source that is becoming an alternative to burning fossil fuels that
may harm the environment during operations due to the emission of harmful gases. In this
study, simulation and performance investigations of a counter-rotating vertical axis wind
turbine (VAWT) based on the Savonius S-type rotor have been analysed through a
computational simulation approach. The foremost motive of this study is to widen the
operating wind speed range of the counter-rotating concept in a VAWT while enhancing the …
