摘要
本文应用全区域计算和利用点对称性的半区域计算两种方法对二维封闭空间中的自然对流进行了数值分析．讨论了雷利数对流场和温度场的影响．并从改善计算方法出发，对两种方法的计算精度和计算速度作了分析比较．
In this paper, using two methods --all domain calculation and half domain calculation by means of point symmetry, natural convection in a two--dimensional enclosure is numerically analyzed. The influence of Rayleigh number on the stream field and temperature field is discussed. The comparison between accuracies and computational times of two methods is made for an improvement on calculation method.
