Modelling of turbine blade-induced turbulence (BIT) is discussed within theframework of three-dimensional Reynolds-averaged Navier-Stokes (RANS) actuatordisk computations. We first propose a generic (baseline) BIT model, which isapplied only to the actuator disk surface, does not include any modelcoefficients (other than those used in the original RANS turbulence model) andis expected to be valid in the limiting case where BIT is fully isotropic andin energy equilibrium. The baseline model is then combined with correctionfunctions applied to the region behind the disk to account for the effect ofrotor tip vortices causing a mismatch of Reynolds shear stress between short-and long-time averaged flow fields. Results are compared with wake measurementsof a two-bladed wind turbine model of Medici and Alfredsson [Wind Energy, Vol.9, 2006, pp. 219-236] to demonstrate the capability of the new model.
