一、前言 近年来,叶轮机械三维流场的数值模拟作为气动设计中流场校核和诊断的手段,已经在实际工程问题中得到有效地应用。(目前,在轴流压气机设计的工程应用中,仍以三维Euler方程方法和带拟粘性力项的Euler三维解法为主。在许多情况下Euler解法所给出的压力分布与实验测量结果有较好的吻合程度)。本文的目的是试图建立一种有效的跨音速压气机叶排中无粘三维流场的计算方法,以便为这类机器气动设计的校核计算
I. Introduction In recent years, the numerical simulation of the three-dimensional flow field of the impeller has been effectively applied in practical engineering problems as a means of flow field check and diagnosis in pneumatic design. (At present, the three-dimensional Euler equation method and the Euler three-dimensional solution with quasi-viscous force are still the main applications in the design of axial-flow compressor, and in many cases the pressure distributions and experimental measurements given by Euler’s method A good degree of agreement). The purpose of this paper is to try to establish an efficient non-sticky 3D flow field calculation method for transonic compressor blades in order to check the aerodynamic design of such machines
