采用ＣＩＭＰＬＥ算法、ＳＩＭＰＬＥＲ算法和ｋ－ε双方程模型，对带运行顶盖封闭方腔内的二维湍流流场进行了数值计算，得到了与实验结果比较一致的计算结果。计算结果表明，ＣＩＭＰＬＥ算法适合带回流的湍流流场的数值计算，ＣＩＭＰＬＥ算法比ＳＩＭＰＬＥＲ算法具有更好的收敛性，是一种值得在工程上推广应用的算法。
The CIMPLE, SIMPLER and k-ε two-equation models are used to calculate the two-dimensional turbulent flow field in a closed cavity with a running roof. The calculated results are in good agreement with the experimental results. The results show that CIMPLE is suitable for numerical calculation of turbulent flow field with backflow, and CIMPLE has better convergence than SIMPLER, which is worthy of popularization and application in engineering.
