两种典型离心压缩机叶轮内部流动的计算与分析

Calculation&Analysis of Internal Flow for Two Typical Centrifugal Compressor Impeller

利用工程上广泛应用的流线曲率法对两种高性能的离心压缩机叶轮进行了详细地计算分析 ,比较了叶轮从进口到出口不同测量截面上的速度分布 ,探讨了高性能离心压缩机叶轮内部流动的发展规律 ,并对理论计算与实验结果的差别进行了分析。

The detailed calculating and analysis are carried out on two centrifugal compressor impellers with high performance by streamline method of curvature used widely in engineering.Velocity distributing on various measuring section from inlet to outlet of impeller are compared.The developing laws of internal flow in centrifugal compressor impellers are discussed.The cause of deviation between theoretical calculation and experimental results are further studied.
