【摘要】 本文发展了一种解叶栅全三维粘性反问题的新的数值方法.基于非正交曲线坐标与相应的非正交速度分量下完全守恒型的Navier－Stokes方程,全三维反问题规定叶片表面的无量纲压力分布反求叶型。计算中叶片表面的边界条件采用一种特殊的方式来处理，即一方面强加给定的压力分布条件,另方面叶面的几何位置在迭代过程中又是可移动的，其移动速度将与Navier—Stokes方程在当地的解联系起来，从而形成一种解定常问题的新的不定常过程.试算证明了本文方法的可行性。更多还原

【Abstract】 Basedon the Navier-Stokes equations in conservative form expressed with nonorthogo nal curvilinear coordinates and nonorthogonal velocity components, a new numerical method for solving fully 3D viscous inverse problem of turbomachinery blading has been developed.In fully 3D inverse problem, the pressure distributions on blade surfaces are prescribed forobtaining the corresponding blade profile. A special treatment is employed to satisfy thegeven conditions. In computational process, an initial blade profile is supposed at starting,and then the blade surfaces will move regularly with time steps until the convergence isreached.更多还原
