Abstract The wind field of wind turbine considering 6 yaw angles (0, 5, 10, 20, 30 and 45 degrees) under the worst blade stop position was simulated based on computational fluid dynamics (CFD) method in order to analyze the flow field characteristics and aerodynamic performance of large-scale wind turbines under complex operating conditions in severe storms and rainstorms. A 5 MW wind turbine researched independently by Nanjing University of Aeronautics and Astronautics was taken as an example. The discrete phase model (DPM) was added and the wind-rain coupling synchronous iterative calculation was conducted. Then the effects of different yaw angles on the characteristics of wind field and rain field around wind turbines were analyzed. The new models of wind-rain equivalent pressure coefficient were constructed, and corresponding calculation formulas were presented. The equivalent pressure coefficient of tower and blades were systematically analyzed for different yaw angles conditions under wind and rain interaction. Results show that the effect of additional rain load on the pressure on the windward side of the blade and the 40 degrees on both sides of the windward side of the tower cannot be neglected.

风雨下考虑偏航效应风力机流场及气动载荷
为了研究狂风暴雨环境中大型风力机在复杂工况下的流场特性和气动性能，以南京航空航天大学自主研发的5 MW风力机塔架-叶片体系为例，采用计算流体动力学（CFD）技术开展最不利叶片停机位置下考虑6个偏航角（0°、5°、10°、20°、30°和45°）影响的风力机风场模拟，添加离散相模型（DPM）开展风-雨耦合同步迭代计算，对比研究不同偏航角对风力机周围风场和雨场特性的影响规律. 建立不同偏航角下的风-雨等效压力系数新模型，给出相应的公式，针对风雨作用下的不同偏航角工况塔架和叶片表面等效压力系数进行系统分析. 研究结果表明，附加雨荷载效应对该类风力机叶片迎风面和塔架迎风面两侧各40°区域内压力的影响不容忽视.
