Abstract

Wind turbines are commonly placed in complex terrain meaning that they may work under conditions of e.g. high turbulence level. This and other effects may give rise to that the turbine works under yawed inflow with respect to the turbine disc plane during a large fraction of its operational time. In this paper we show how the inflow towards the rotor disc is affected by yaw through PIV measurements.
