A quasi-three-dimensional aerodynamics design method for the wind turbine with brimmed diffuser has been developed. The design method is based on two-dimensional blade data and an axisymmetric meridional flow analysis. In the meridional flow analysis the axisymmetric flow is computed on a meridional plane, including the viscous forces and the aerodynamic blade loading modeled by the blade forces, in order to take the spanwise distribution of the inlet flow into account. The flow fields in the wind turbine designed by the present method have been investigated by three-dimensional Reynolds-averaged Navier-Stokes (RANS) simulations. It is shown that the performance of the wind turbine depends on the blade loading.
