用于捕获两种流体之间的界面的水平集方法与变密度投影方法相结合，以允许计算两相流，其中界面可以合并/破裂并且流可以具有高雷诺数。水平集方法的距离函数公式使我们能够计算具有大密度比（1000/1）的流动和表面张力驱动的流动，没有情感参与。最近的工作提高了距离函数公式的精度和平流方案的精度。我们计算涉及气泡和水滴等的流动。我们验证我们的代码对实验和理论。(C)1998爱思唯尔科技有限公司版权所有。
A level set method for capturing the interface between two fluids is combined with a variable density projection method to allow for computation of a two-phase flow where the interface can merge/break and the flow can have a high Reynolds number. A distance function formulation of the level set method enables us to compute flows with large density ratios (1000/1) and flows that are surface tension driven, with no emotional involvement. Recent work has improved the accuracy of the distance function formulation and the accuracy of the advection scheme. We compute flows involving air bubbles and water drops, among others. We validate our code against experiments and theory. (C) 1998 Elsevier Science Ltd. All rights reserved.
