Interface-capturing method on quadtree-based adaptive Cartesian grid
Wang Sheng-hu · 2014
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.
