摘　　要：以麦克马斯特大学H型垂直轴风力机为基础,在叶片上加设射流管,设计一种叶片失速延迟控制垂直轴风力机。基于CFD方法计算典型工况下叶片失速延迟控制垂直轴风力机的功率,分析风场的涡强和风速分布特性。研究结果表明:在相同几何尺寸和工况下叶片失速延迟控制风力机的风能利用系数比麦克马斯特大学H型垂直轴风力机的高,在尖速比为1.3时,最大风能利用系数达到0.33。在叶片上加设射流管对于延迟层流分离具有显著作用。Through adding a jet pipe on the blade, a blade stall delay control vertical axis wind turbine was designed on the basis of Mc Master university H-type vertical axis wind turbines. Employing CFD method, the power of blade stall delay control vertical axis wind turbine was calculated under the typical working conditions, and the vorticity and wind speed distribution characteristics were analyzed. The results show that with the same geometry size and the working conditions, the wind energy utilization coefficient of blade stall delay control wind turbine is higher than that of Mc Master H-type vertical axis wind turbines. The maximum wind energy utilization coefficient reaches 0.33 when the tip speed ratio is 1.3. Adding jet pipe on blade has significant effects on delaying laminar flow separation.
