摘要

To improve the utilization rate of wind energy on Savonius wind turbines, this study proposes an impeller scheme with different bilateral contour and optimizes bilateral shape parameters. Based on the Reynolds averaged N-S equations and SST k-ω turbulence model, the computational fluid dynamics (CFD) model of numerical calculation is established using the sliding mesh technique. Then, the kriging-PSO optimization model of the wind turbine impeller with bilateral contour is developed. Finally, the CFD and kriging-PSO optimization models are used to optimize the bilateral shape of the Savonius wind turbine impeller. Results show that the impeller with shape parameter of (0.626 8, 0.541 3) has the highest efficiency (0.284), which is 7.17% more than that of the conventional Savonius impeller (0.265).
