摘要

运动界面的追踪是两相流模拟中需要解决的主要问题之一。基于四叉树直角坐标网格实现了Level set界面追踪方法和网格的局部自适应控制。通过模拟3个给定速度场（平移流场、旋转流场、剪切流场）的运动界面追踪问题，证明了自适应四叉树直角坐标网格与Level set方法结合的优势。

Abstract

Capturing the moving ingerface is one of the critical issues in the simulation of two-phase flows. In this paper

a moving interface capturing method based on the level set method and the quadtree grid is preseated

in which the grid is locally and self-adaptively controlled. It is validated from three moving interface problems with the given velocity field of translational flow

rotational flow and shear flow that the combination of the Level set method and the quadtree grid is more efficient and accurate.
