A coupled aerodynamic design method of turbine rotor and wind-lens has been developed by the use of genetic algorithm which is one of the optimization methods. The present design method is based on two-dimensional blade data and an axisymmetric meridional viscous flow analysis. The axisymmetric meridional viscous flow analysis shows that the coupled design for wind-lens turbine using the genetic algorithm achieves higher performance and wind collecting coefficient than the conventional design for turbine rotor only. The three dimensional flow fields of the wind-lens turbine have been investigated by three-dimensional Reynolds-Averaged Navier-Stokes (RANS) simulation. Also, the three dimensional flow analysis results show that the coupled design method is superior to the conventional design method. It is found that the aerodynamic blade loading distributions and wind-lens shape have an effect on wind-lens turbine performance, wind collecting coefficient and three dimensional flow fields around wind-lens turbine.
