摘要
本文利用坐标变换将物理平面上任意形状的区域变换到计算平面上规则的区域。并对任意放置的梯扇形闭包内的自然对流、多孔介质中流体的流动和传热以及空腔强迫对流三种情况用涡量-流函数法进行了计算。利用编制的数据处理软件对计算结果进行了处理。
Using Coordinate Transformation, the arbitrary shaped physical domains are mapped onto the normal computational domains and three examples about heat transfer and fluid flow are calculated with the Vorticity-Stream Function method. During the calculation, the concept of computational velocity is introduced. Four different schemes, which are conservative/noncon-servative central difference and conservative/nonconservative upwind difference, are Seperately used. In computation, the values of the vorticities on the walls are temporarily fixed, the parameters which are dominant in the governing equations are gradually increased and Double-Grid Method is used to save the CPU HOURS. The iterative sweeping is carried on along the four different directions. The computation results are compared with those by SIMPLE Method. The datum is conducted using some programs that can be adapted to common printers, graphic printers and graphic plotters.
