摘　　要：为了改善H型垂直轴风力机的启动性能,本文提出了一种表面装有半球形凸粗糙元叶片的H型垂直轴风力机,并对单面装有凸粗糙元叶片的H型风力机进行风洞试验,分别测试了H型风力机在多个风速下的静扭矩特性以及动态启动特性,得出了凸粗糙元对H型风力机启动性能的影响规律。试验结果表明:采用凸粗糙元外置叶片的H型风力机静扭矩增大,启动时间减小,最大稳定转速增大。In order to improve the start-up performance of the H-type vertical axis wind turbine,this paper proposes an H-type vertical axis wind turbine with hemispherical convex roughness element blades.A wind tunnel test on the H-type wind turbine with convex roughness element blades on one side is conducted.The static torque characteristics and dynamic start-up characteristics of the H-type wind turbine under multiple wind speeds are tested respectively,and the influence rules of the convex roughness element on the start-up performance of the H-type wind turbine is obtained.The test results show that taking the convex roughness element blade,the H-type wind turbine increases the static torque,decreases the start-up time,and increases the maximum stable rotate speed.
