摘　　要：本文利用κ-ε湍流模型方法和叶轮进出口测试结果计算离心叶轮内部流动。计算采用了SIMPLEC方法,对压力修正方法进行了适当改进。为适应可压缩流动计算的需要,利用局部摩擦损失建立了压力与密度的联系。文中给出了两个叶轮的计算结果。A method using κ-ε turbulence model theory is proposed in this paper for solving the flow field in the centrifugal compressor impellthe flow. On the basis of this fact, the argue th which the SIMPLEC was used. In order to calculating compressible flow, author related the variation of stage pressure and density by means of the friction loss and polytropic efficiency. The computing results of internal flow field in two impellers are given in this paper.
