用CIMPLE算法计算带运动顶盖封闭方腔内湍流场

Application of Cimple Scheme to Numerical Calculations of Turbulent Flow Field in Lid-driven Cavity

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。

In this paper, the proposed CIMPLE scheme and the SIMPLER scheme are applied to the numerical calculations of the two-dimensional turbulent flow field in the lid-driven cavity, the calculation results show that the CIMPLE scheme is suitable to numerical calculations of the re-circulating turbulent flow. It presents better convergence than the SIMPLER scheme.
