摘要
旋转流存在着强烈的各向异性湍流。运用通常的各向同性湍流模型，如Ｋ—ε方程，对于旋转流是不合适的。本文应用了具有理查德数修正的Ｋ—ε方程．计算机算法是ＩＭＰＬＥ，它避免了ＳＩＭＰＬＥ和ＳＩＭＰＬＥＲ的某些缺陷。计算结果表明：修正的Ｋ—ε方程对于计算旋转流是适合的．
There esists strong anisotropic turblence in the rotaing flow It is inappropriate to utilize usualisotropic turbulence model,as K εequation, for rotating flow.Corrected K εequation with Richardsonnumber is used in this paper.The argorithm is IMPLE,which eliminates some shortcoming of argorithmSIMPLE and SIMPLER.The numerical results indicate that corrected K εequation is appropriate forcomputing rotating flow.
