CFD simulation of violent free surface flows by a coupled level-set and volume-of-fluid method Conference Paper

abstract

• A coupled level-set (LS) and volume-of-fluid (VOF) method has been developed for time-domain simulation of violent free surface flows around two- and three-dimensional structures. The advection of the VOF function is performed using a mixed second-order Eulerian and Lagrangian scheme with a piecewise linear interface calculation (PLIC). A mass correction scheme is implemented to compensate for the mass change and maintain a divergence-free velocity field. The level-set function is solved using a fifth-order Weighted Essentially Non-Oscillatory (WENO) scheme. The coupled level-set and volume of fluid (CLSVOF) interface-capturing method is employed in conjunction with the Finite-Analytic Navier-Stokes (FANS) method for time-domain simulation of violent free surface flow problems. Moreover, a chimera domain decomposition approach is implemented using an overset grid system including embedding and overlapping grids for accurate resolution of flow around structures. The simulations results demonstrated the capability of the CLSVOF method in maintaining mass conservation for violent free surface flow problems.
