摘　　要：针对车用涡轮增压器的唯一对气体做功的部件——叶轮,应用ANSYS CFX软件数值模拟的方法,对离心压气机内部流场进行研究,分析叶轮各结构参数对压气机性能的影响,并将模拟计算结果与性能实验数据进行对比分析,为选取显著性结构参数、进行叶轮优化设计提供理论支撑。The study of the flow field and compressor characteristics of the automotive turbocharger centrifugal compres- sor were carried out with ANSYS numerical simulation method. The analysis of the effect of impeller structure parameters on the compressor performance was also performed. The simulation results were analyzed and compared with the experimental data, which could provide theoretical support for selecting significant structural parameters and optimizing the design.
