摘要
A theoretical investigation of the effects of dynamic stall and flow curvature on the aerodynamic performance of vertical-axis straight-bladed Darrieus wind turbines is presented. The dynamic stall and flow curvature effects are added to the cascade model for the analysis. The experimental data and the calculated values of the instantaneous blade forces and the wake velocities show good correlation in most of the cases.
