中文摘要：

利用五孔探针对离心压缩机蜗壳内部的三维流动进行了详细的测量，在此基础之上，着重对圆形截面偏心蜗壳内部三维流场的流动过程进行研究与分析，旨在为把握其三维流动的生成演化细节和积累流动图谱等基础性资料，为今后蜗壳设计与改良提供可靠数据并打下良好基础。

英文摘要：

The flow in a centrifugal compressor volute, which has a cirular cross section, has been measured in detail by means of the five - hole probe. With analysis of the measured data, the process of the flow in a centrifugal compressor volute with circular cross section has been described. And got some result in this kind of flow. The measurements and analysis in this thesis are of some universal significance, they are help to the further research and design on the flow.
