摘要：

In order to calculate the aerodynamic performance of vertical axis wind turbine blades under dynamic stall, 2 dynamic stall models, B-L model and MIT model, were modified in detail based on actual working conditions of the wind turbines. Taking a vertical axis wind turbine with a height of 17 meters in Sandia laboratory as an example, dynamic tangential force coefficient and dynamic normal force coefficient of the blade were calculated based on the 2 models above when the blades tip speed ratio was as 2.33 and 3.09 respectively. The research results show that the MIT correction model has higher prediction accuracy for the tangential force coefficient in windward areas and the normal force coefficient in the leeward areas, and the B-L correction model has higher prediction accuracy for the normal force coefficient in the windward areas and the tangential force coefficient in the leeward areas. © 2019, China Mechanical Engineering Magazine Office.
