中文摘要：

三维面元法利用面网格实现三维势流流场的求解，不但可以准确地计算压力系数分布等叶片三维流场信息，又不需要耗费过多的计算时间，为分析风力机三维流场提供了有效的途径。边界层模型可以有效地计算近壁黏性区，从而补充面元法的不足。基于三维面元法和二维边界层模型建立黏性无黏耦合模型，并以Joukowsky翼型为案例验证面元法模型准确性。利用黏性无黏耦合模型对NRELPhaseVI风力机叶片的三维流场进行了具体的分析。计算结果表明黏性无黏耦合模型具有效率高计算准确等特点，适合于风电叶片气弹耦合问题的研究。

英文摘要：

The 3D Panel Method can obtain the 3D potential flow field just by the surface mesh attached to the wind turbine blade and give accurate pressure coefficient distribution et. 3D flow information without consuming too much computational time. So the 3D Panel Method provides an efficient access to the analysis of 3D flow field of HAWT. The boundary layer model is an efficient method for analyzing the viscous flow near the blade, which provides suitable complimentary for the Panel Method. Based on the 3D Panel Method and the 2D boundary layer model, a viscous and inviscid interaction model is created in this paper. After validating the accuracy of 3D Panel Method by the case of the potential flow field around the Joukowsky airfoil, a detailed analysis of the 3D flow field of NREL Phase VI wind turbine blade is carried out. The results show that the interaction model is efficient and accurate, so that it is suitable for the study of aeroelastic problem of HAWT.
