| 摘 要： | 本文应用常规的守恒方程及湍流模型，对二维池内热分层流动建立了数学模型，并在Ｐａｔａｎｋａｒ的压力校正法基础上对该数学模型进行了数值计算，计算中的差分格式为乘方格式、一阶迎风、二阶迎风和ＱＵＩＣＫ。通过与实验的比较分析，建议计算应采用ＱＵＩＣＫ格式，并在进行风格独立性试验的基础上使用加密网络。

| Abstract: | The conventional conservation equations and turbulence model are applied to construct mathematical model of 2-D thermal stratified flows in a pool. The equations are numerically solved in a base of the method of Patankar. For the differrence schemes of the computation PLDS, First and Second order upwind and QUICK are tested. From the comparisons QUICK is recommended and finer grids should be used after the grid independence test being made. |
