一、前言 中心流面法和中心流线法一样,都是使用级数展开,从一流面(线)出发进行全流场计算.和中心流线法相比,中心流面法发展较晚.文献[1]首先使用逐个S_2流面推广展开的方法实现了文献[2]提出的使用中心流面法求解全三元反问题的想法.文献[3]进一步引入了流面坐标系,实现了直接从中心S_2流面高阶展开.本文把这种方法推广,进一步使用中心流面法求解轴流式叶轮机械全三元流动正问题.
I. INTRODUCTION Like the central streamline method, the central streamline method uses the series expansion to calculate the full flow field from the first-class surface (line), and the central stream surface method develops later than the central streamline method. [1] Firstly, the idea of solving the all-ternary inverse problem using the central flow-surface method proposed in [2] was first implemented by using S 2 flow surface expansion and expansion. Reference [3] further introduced the flow surface coordinate system to realize direct From the center S_2 flow surface high-order expansion.This paper extends this method to further use the central flow surface method to solve the axial flow impeller mechanical full ternary flow problem.
