内容摘要Abstract

We present an interface conforming method for simulating two-dimensional and axisymmetric multiphase flows. In our method, an interface is composed of linear segments which move with the flow while remaining a part of the mesh system. This interface representation is an integral part of an Arbitrary Lagrangian-Eulerian (ALE) method on an adaptive moving unstructured mesh. Dynamic boundary conditions on interfaces, are therefore incorporated naturally and accurately in a finite-element formula. The accuracy and effectiveness of our methods will be demonstrated through a wide range of the applications to drop/bubble dynamics.
