An Anti-Diffusive VOF Method for Computational Modelling of Sloshing in an LNG Tank

摘要

A new VOF method is presented comprising of a combination of the first order limited downwind scheme with other high order accurate schemes. The method developed is characterized by keeping a sharp interface but avoids complicated geometrical reconstruction as occurs in most volume tracing algorithms. To demonstrate the accuracy and robustness of the method, a selection of numerical experiments are presented involving a pure advection problem, a water wave impact caused by a dam breaking and liquid sloshing in a partially filled tank.
