离心式压缩机叶轮子午面流场的边界元分析

The Boundary Element Analysis for the Meridional Flow in Centrifugal Compressors Impellers

本文提出一种计算离心式压缩机叶子午面流场的方法。采用密度加权周向平均方程,引入流函数,利用迭代法将其化为泊桑方程,然后用边界元法求解。计算结果与实验结果进行了比较。

A method for solving the meridional flow equations in a centrifugal compressor impellers is presented. The density weigted pitchaveraged equations are atopted. The stream function equations may he transformed into Poisson equations after using the iteratire method are solved by the B. E. M. The calculated results are compared with the experimental results.
