| 摘 要： | 采用Kirchhoff方法计算NACA0012翼型的远场气动噪声,Kirchhoff面为包围整个翼型的一层网格。首先采用欧拉方程计算程序求解得到翼型的Kirchhoff面上在桨尖涡干扰下的近场气动流场解,再根据Kirchhoff方法求解远场声压。从而体现出在计算桨涡干扰噪声时,旋翼CFD技术与Kirchhoff方法相结合的良好效果。

| Abstract: | The far field noise generated by NACA0012 airfoil/tip vortex interaction is predicted using the combined Euler/Kirchhoff method. Kirchhoff surface is selected as one of the grid surfaces.Firstly,the result of nearfield can be obtained by solving Euler equations.Then the result of farfield can be calculated by Kirchhoff method.Finally, the combined Euler/Kirchhoff method developed here is proved a good try for studying Blade Vortex Interaction (BVI) noise through sample calculations. |
