一种新的自适应网格方法,并应用在存在静止或移动物体的二维流场数值模拟。应用该方法并不产生新的节点和单元,并且不用插值就可以精准地计算物体与流体交接面的应力。该方法应用在有静止与转动的圆柱绕流问题,计算结果与相关试验结果符合较好。

A new adaptive mesh method,and applied in numerical simulation of two-dimensional flow fieldof stationary or moving objects.This method does not create a new node and the unit,and can accuratelycalculate the stress of transfer from the object and the fluid surface without interpolation.when this methodis used solving the questions of a stationary and rotating cylinder flow,the calculation results are in good agreement with the related experimental results.
