一、前言 叶轮机械三元流动通用理论提出的使用两类流面迭代求解叶轮机械三元流动正反问题的方法,已成为内流数值计算的一个基本方法。随着计算机速度的提高、内存的扩大,越来越多的三元直接解投入了使用。但是两类流面迭代求解仍然是叶轮机械内流计算的一个重要方法。
I. INTRODUCTION The method proposed by General Theory of Impeller Mechanical Flow for Three-Dimensional Flow to solve the forward and inverse problem of the ternary flow of impeller using two types of flow surface iteration has become a basic method of numerical calculation of internal flow. As computer speeds increase and memory expands, more and more ternary direct solutions are put into use. However, the iterative solution of two kinds of flow surfaces is still an important method for the calculation of impeller internal flow.
