摘要:本文根据已有的三维瞬态风场混合数值模拟方法，首先利用k-ε湍流模型对风力发电机叶片周边的时均湍流场进行CFD数值模拟，用ESDU推荐的方法计算了叶片附近的Reynolds应力张量，并修正叶片周边风场的脉动风功率谱密度函数。基于随机流场生成方法逐点模拟了叶片周边的三维脉动风速场，为今后进行叶片脉动荷载的求解奠定了基础。
Abstract: Based on a hybrid numerical simulation method of the three-dimensional fluctuating wind field proposed before, the time-averaged turbulent flow field around a wind turbine blade was calculated by means of k-ε turbulence model. Reynolds stress tensors were calculated with the method recommended by ESDU and were used to modify the power spectral destiny functions of wind velocity. Three-dimensional fluctuating wind velocity field was simulated based on random flow generation method and provided a basis for the solution of the fluctuating wind load of wind turbine blades.
