在这项工作中，我们提出了一种用于多流体和复杂边界问题的守恒界面方法，其中通过考虑计算单元被界面切割来修正笛卡尔网格上的标准有限体积格式。该方法在离散控制方程保守更新的同时，将界面描述和几何运算与水平集技术相结合，自然地处理了拓扑结构的变化。在一维空间中进行了大量的试验，二维算例表明，该格式能够以直观的方式处理多流体和复杂的(静态或运动)边界问题，具有良好的鲁棒性和精度。(C)2006 Elsevier Inc.保留所有权利。
In this work, we present a conservative interface method for both multi-fluid and complex boundary problems, in which the standard finite volume scheme on Cartesian grids is modified by considering computational cells being cut by interface. While the discretized governing equations are updated conservatively, the method treats the topological changes naturally by combining interface description and geometric operations with a level set technique. Extensive tests in 1D are carried out, and 2D examples suggest that the present scheme is able to handle multi-fluid and complex (static or moving) boundary problems in a straightforward way with good robustness and accuracy.
