THE COMPUTATION OF THE FREE VISCOUS FLOW ON THE WAV SLOPE
-
摘要: 利用非定常变换将流体流动的复杂区域变到一个固定的矩形计算区域，然后用高效的数值方法对此强非线性问题进行积分．由于变换本身是随自由面变化而变化，刻画这一变换的参数将作为未知量与其它待求流动参数在积分过程中同时求得．本方法对流动问题不作任何限制，可以计算非常复杂的自由粘性流动问题．Abstract: In this paper a time-dependent transformation which maps the moving flow region into a fixed rectangular is offered, by which the effective computational methods may be used to compute very complex free viscous flow. From the results of the example the important difference were discovered in comparing with the results computated by [1] with simplified equations.
