| 摘 要： | 对半圆域上的自然对流采用控制体有限元方法进行数据模拟，采用非结构三角形网格与质量加权迎风格式对计算域及控制方法进行离散，对压力离散方程采用波前法求解，保证了对所有Ra≤10^7时迭代过程的收敛性。

| Abstract: | It presents details of the results of natural-convection flowsfor Ra≤107 on semicircular cavity. The control-volume finite-element method based on unstructured grids and mass-weighted upwind scheme is employed to discretize governing equations, and the fronts method is employed to solve the pressure discretization equations. For all of Ra≤105, the present results are very agreement with the previous literature, and for Ra=106、107, the iterations have not run into the difficulty of convergence. |
