我们在场为模仿多重 unmixable 液体移动的一个新奇基于格子的方法;交往。不同于以前的方法,那能仅仅代表在二液体之间的接口(通常在液体之间;气体) ,这个方法罐头通过结合的多重独立水平集合处理液体的一个任意的数字一个 constrain 条件。为了捕获液体,更精确地出现,我们扩大粒子水平集合方法到一个多液体版本。它分享粒子水平集合方法的优点,;有能力追踪多重液体的接口。处理一起存在的不同液体的动态特性,我们基于一个光滑的加权函数使用多相的液体明确的表达。
We present a novel grid-based method for simulating multiple unmixable fluids moving and interacting. Unlike previous methods that can only represent the interface between two fluids (usually between liquid and gas), this method can handle an arbitrary number of fluids through multiple independent level sets coupled with a constrain condition. To capture the fluid surface more accurately, we extend the particle level set method to a multi-fluid version. It shares the advantages of the particle level set method, and has the ability to track the interfaces of multiple fluids. To handle the dynamic behavior of different fluids existing together, we use a multiphase fluid formulation based on a smooth weight function.
