Aerodynamic characteristics of blade stall delay control vertical axis wind turbine
摘要
Abstract
Through adding a jet pipe on the blade, a blade stall delay control vertical axis wind turbine was designed on the basis of McMaster 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 McMaster 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.关键词
