矩形管道内充分发展热流动的可视化计算

Visual computation of developed heated fluid flow in a rectangular pipe

推导了求解矩形管道内充分发展流体流动和热交换的有限差分方程,编写了相应的计算机程序,借此求得了管道横截面内速度和温度的结点值,然后利用计算机图形显示算法自动生成相应的速度和温度等值线图形.最后,对管道内充分发展热流动的特性进行了讨论.

The finite difference equations of fully developed fluid flow and heat transfer in a rectangular pipe are established, and the corresponding computer program is compiled to solve the velocity and temperature on grid nodes in pipe cross section. Then the equivalent-temperature lines of velocity and temperature are automatically drawn by graphic display algorithm. Finally, the characteristics of velocity and temperature of heated fluid flow in pipes are discussed.
