小流量离心制冷压缩机级内流动的CFD分析
CFD Analysis of Stage Flow in Small Flow Centrifugal Refrigeration Compressor
摘要
Abstract
Compressor is the core component of the vapor cycle cooling system, this paper uses FLUENT software and calls the real gas model then read the R134a state parameter to simulate and analyze the internal flow of small flow centrifugal compressor, which enhances the quality of simulation to a certain extent. Compared with experimental results, the simulation result is closed so can be considered to be right. The analysis shows that: Using FLUENT software to analyze the internal flow of small flow centrifugal refrigeration compressor is feasible; the outlet of impeller may occur two times flow phenomenon; The flow at the top of the diffuser inlet is unsteady, which causes large flow loss, and the internal flow of diffuser is not uniform. Then finally gives several corresponding optimization suggestions.关键词
