Abstract

The present work is devoted to develop a numerical wind tunnel to study the wind turbine wake in turbulent boundary layer flow by using large eddy simulation (LES). The turbine induced forces, including thrust and torque force, are modeled by using the actuator disk model with rotation (ADM-R). Characteristics of mean and turbulence in the wake of miniature as well as real scale wind turbine are examined and compared well with the experiment data. A new analytical wake model based on the numerical simulation result is proposed by systematical analysis of the ambient turbulence intensity and thrust coefficient of rotor. The velocity deficit and turbulence increment in the wake predicted by the new wake model show favorable agreement with the LES data both in near and far wake region.
