摘要：
This paper presents the results of the power performance prediction of H-shaped vertical axis wind turbines using a lifting-line free vortex wake model cooperating with the Leishman-Beddoes (LB) dynamic stall model and semi-empirical equations accounting for strut loss. The power performance curves of two turbines with different diameter and solidity are compared with measurements. It is shown that the dynamic stall effect is obvious when tip speed ratio is less than 4. In general, the strut loss increases with tip speed ratio, the maximum value is 60% and 35% respectively for two turbines. For H-shaped wind turbines with low solidity, the model can give a good prediction of the power performance, while for H-shaped wind turbines with high solidity, the model improved. © 2022, Solar Energy Periodical Office Co., Ltd.
