一种自适应网格方法及其在流场中存在任意静止移动物体问题的应用

The application of an adaptive grid method and its presence in the flow field at any stationary moving objects

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.
