本文从径流式叶轮机械蜗壳的非轴对称流场原理出发,研究离心压气机蜗壳在变工况时非轴对称流场的特性.本文是“离心式压气机扩压器与蜗壳非轴对称流场的计算与分析”一文的继续.在本文中,进一步研宄了蜗壳舌部在变工况时对蜗壳非轴对称流场的显著影响.计算与实验结果表明,由于考虑了舌部的影响,使论文中提出的方法在相当大的变工况范围也能得出相当满意的结果,为研究压气机叶轮在变工况时的特性提供了依据.
In this paper, based on the principle of non-axisymmetric flow field of radial turbine impellers, the characteristics of non-axisymmetric flow field of centrifugal compressor volute in variable working conditions are studied.This paper is a study on the characteristics of centrifugal compressor diffuser and volute non- Axisymmetric Flow Field Calculation and Analysis "continued in this article, further study of the volute tongue in the variable condition of non-axisymmetric flow field of the volute significant impact calculated and experimental results show that due to consider The influence of the tongue makes the method proposed in the paper also get quite satisfactory results in a large range of working conditions, which provides a basis for studying the characteristics of the compressor impeller in variable working conditions.
