复杂区域流动换热问题的一种新的网格处理方法

Computation of FLow and Heat Transfer Problems in Complex Region

在阶梯形网格法的基础上发展了一种二维复杂区域流动与换热问题的新的数值方法．该法采用了同位网格下的ＳＩＭＰＬＥＮ算法，并借鉴了非结构化网格技术来进行复杂计算区域的网格划分及组织计算．用这种方法计算了方腔内的自然对流及圆内开缝正方形加热环体的自然对流，取得了很好的效果．

An new method is developed for computing two dimensional flow and heat transfer problems in complex geometries. The SIMPLEN algorithm is adopted, and an unstructured grid like grid system in cartesian wordionates is developed to deal with irregular boundaries. Two typical examples of natural convection in enclosure are presented.
