【摘要】 使用NUMACA软件对两个不同流量系数的离心式压缩机级静子元件中的流动进行了数值模拟。分析了两个级无叶扩压器中的流场及其中一个级弯道和回流器中的流场。对离心式压缩机级设计提供了改进信息。更多还原

【Abstract】 Numerical simulation of flow is carried out on static components of 2 stages of centrifugal compressor whose flow coefficient are different using NUMACA software. It analyzes the flow field of vaneless diffuser of 2 stages and the bend and return channel for 1 stage. The information how to improve the stage design of centrifugal compressor stage is put forward.更多还原
