摘要 该文根据Level Set方法和VOF方法各自的优缺点,提出一种耦合的界面捕捉方法。该方法利用混合网格的体积份额确定混合网格的距离函数,从而达到提高Level Set方法捕捉运动界面的分辨率、改善守恒性的目的。通过给出的旋转流场和剪切流场的数值算例,说明了本文所提方法的有效性。 Based on the advantages and disadvantages of Level Set method and VOF method,this paper presents a coupled interface capturing method.In order to improve the resolution of the capturing interface,the distance function of mixed grid is determined by the volume fraction of the mixed grid.The numerical results of the applied cases show that the interface capturing method is effective and feasible.
