摘要
详细分析了离心压缩机轴向力的组成，建立了离心叶轮外侧间隙内泄漏气体流动的计算模型，采用了低Ｒｅ数ｋε模型，用ＳＩＭＰＬＥＣ方法求解控制方程．对１台离心压缩机的轴向力进行了计算，结果令人满意．
Examined are the axial thrusts acting on the impeller of centrifugal compressor. The compute model gives to the leakage gas flow field in the gap outside of the impeller. Results are obtained use of low Reynolds number k ε turbulence model together with the SIMPLEC algorithm. Satisfactory results are found for the axial thrust of centrifugal compressor.
