数值模拟界面流方法进展

ADVANCES IN NUMERICAL SIMULATION OFINTERACIAL/FREE-SURFACE FLOWS

用数值模拟方法研究界面流;对于工程设计和理论分析复杂流动都是非常重要的．单纯用现有的高分辨格式无法清晰定出流体界面,故此对界面必须进行特殊的处理,例如界面跟踪(fronttracking)方法．本文对界面流的各种数值模拟方法进行了综述．这些方法包括锋面跟踪法、移动网格法、基於粒子法、边界积方法、连续对流格式、体积跟踪方法和水平集的方法．我们着重介绍了现阶段处理流体界面问题使用较多的方法:体积跟踪方法和水平集方法．同时我们也对各种方法的优缺点作了评述．

Numerical simulation of interface/free-surface flows is important both in research anddesign. If we only use the high-resolution scheme, we can't get the clear interface, and so we mustdeal with the interface specially In recent decades, Eulerian methods have made a profound de-velopment in simulating interface/free-surface flows. In this paper, we introduce various methodsin simulation of interfacial /free-surface flows, and we also discuss the limitations of each method.These methods include front tracking, moving mesh, based-particle, boundary integrating, contin-uum advection, volume tracking and level set. In particular, we pay more attention to the volumetracking methods and the level set methods.
