一、前言 在风扇发动机中,内外涵分流环的形状与位置会对风扇发动机的性能有明显的影响.因而,了解分流环表面的速度、压力等的分布以及其对流场的影响,对于提高风扇发动机的性能具有重要的实际意义. 本文所介绍的这个计算程序采用任意非正交曲线坐标与相应的非正交速度分量的叶 I. INTRODUCTION In the fan engine, the shape and position of the circulation ring inside and outside the divider will have a significant effect on the performance of the fan engine. Therefore, knowing the distribution of the velocity and pressure on the surface of the split ring and its influence on the flow field, The performance of a fan engine is of great practical importance.The computational procedure presented in this paper uses the leaves of any non-orthogonal curvilinear coordinate with the corresponding non-orthogonal velocity component
