分别用带转捩模型的边界层耦合计算方法和基于RANS方程的通用CFD方法对风力机常用翼型S809进行了气动分析。通过自由转捩、强制转捩和全湍流模式的比较,着重阐述边界层转捩点预测对风力机翼型气动性能计算分析的影响。
The aerodynamic analysis of the common wing airfoil S809 of the wind turbine was carried out by the coupled boundary layer method with transition model and the general CFD method based on the RANS equation respectively. Based on the comparison of free turbulence, forced turbulence and turbulent turbulence model, the influence of boundary layer transition forecasting on the aerodynamic performance of wind turbine airfoil is analyzed.
