提出了计算不可压缩两相流解的水平集方法。两种流体之间的界面被认为是尖锐的，并被描述为平滑函数的零水平集。我们使用二阶投影方法来实现二阶迎风过程来区分对流项。水平设置方法的新处理使我们能够包含大密度和粘度比以及表面张力。我们考虑水中气泡的运动和空气中落下的水滴。 (C) 1994 年学术出版社
A level set approach for computing solutions to incompressible two-phase flow is presented. The interface between the two fluids is considered to be sharp and is described as the zero level set of a smooth function. We use a second-order projection method which implements a second-order upwinded procedure for differencing the convection terms. A new treatment of the level set method allows us to include large density and viscosity ratios as well as surface tension. We consider the motion of air bubbles in water and falling water drops in air. (C) 1994 Academic Press, Inc.
