摘要
Level Set方法是近几年研究比较多的一种界面追踪技术。由于非结构网格下高阶WENO格式构造上的困难,至今的研究成果主要是基于结构化网格。把快速步进法和源点扫描法的思想结合起来,用于Level Set的计算,并提出了在非结构网格下的实现方法。最后用剪切流场对算法进行了检验,证明了算法的有效性。对于存在分层界面的两流体的计算有重要的实用价值。
The Level Set Method is the popular technique of interface tracing in the past years. Because of the constructional difficulty of WENO scheme under unstructured grids, the studies about the Level Set Method are mainly based on structured grids. In this paper, the Fast-marching Method and the Source-scanning Method are applied to solve the Level Set , and the scheme is finished under unstructured grids. At last, the scheme is applied to shearing flow. In this paper, the Level Set Method based on unstructured grids is valuable to the calculation of two fluids with interfaces.
