Abstract
In this study we are aimed to simulate incompressible fluid flows with moving interface separating liquid and gas phases. To achieve volume/mass conservation and to capture interface, the interface-capturing volume of fluid (VOF) method, which is exercised in compliance with requirement of volume/mass conservation, will be coupled with the other interface-capturing level-set (LS) method, which is suitable to capture interface accurately. In our proposed advection algorithm, VOF is the building block that solves the volume fraction and the level-set function is solely used to assist an accurate calculation of some geometrically relevant quantities at the interface. A high order scheme developed within the optimized compact reconstruction WENO framework has been applied to solve the advection equation. The novelty of this purposed advection algorithm is attributed to its efficient implementation without sacrifice of computational accuracy.
