Abstract

In the present numerical study, we carried out the large-eddy simulation (LES) of the wake generated behind the wind turbine generator under optimal tip speed ratio. Particular emphasis was placed on the effect of inflow turbulence on the wake region generated behind the wind turbine generator. Through comparisons between three cases with and without inflow turbulence, the speed loss of about 30-40 percent existed in the wake region (1D-5D) in all the cases, where D is a diameter of a rotor.
