摘要
利用改进的SIMPLER算法即环绕主节点的四个小控制体与推广的QUICK差分格式相结合 ,在非均匀同位网格上求解二维非定常流动与传热的控制方程 .以封闭方腔内的层流自然对流换热问题为例进行了数值模拟 ,计算结果与已有文献一致 ,且得出的平均努赛尔数的计算公式较以前的计算公式精度要高 。
A procedure of solving general control equations for unsteady two-dimensional fluid flow and heat transfer is described. QUICK scheme and small control volume are adopted to calculate variables on colocated grid. Improvements on the simpler method are made. The laminar natural convection flow and heat transfer in an enclosed square cavity are calculated for illustration. The results are in agreement with those abtained in references. The calculation equation pricision on average Nu correlations is higher than the former ones, which indicates that the author's method is applicable.
