Webof a VAWT rotor by an infinitely thin rotor plane is to be discussed. Moreover, this assumption requires the comparison of the wake structure of both systems. For HAWTs the wake is convected downstream and dominated by its helical character. Hence, the direct interaction between the shed vortices and the rotor blades is comparably small. There- WebOn the contrary, a vertical axis wind turbine is not so dependent on the wind angle and can operate at a lower wind speed than an average HAWT. However, there are a few horizontal axis wind turbines designs, such as …
