Abstract / Description of output

This paper describes a finite-volume volume-of-fluid (VOF) method for simulating viscous free surface flows on dynamically adaptive quadtree grids. The scheme is computationally efficient in that it provides relatively fine grid resolution at the gas-liquid interface and coarse grid density in regions where flow variable gradients are small. Special interpoiations are used to ensure volume flux conservation where differently sized neighbour cells occur. The numerical model is validated for advection of dyed fluid in unidirectional and rotating flows, and for two-dimensional viscous sloshing in a rectangular tank.
