By treating it as a contact discontinuity in the density field, a free surface between two immiscible fluids can be automatically 'captured' by the enforcement of conservation laws. A surface-tracking method of this kind requires no special tracking or fitting treatment for the free surface, thereby offering the advantage of algorithm simplicity over other free surface methods. In this paper a surface-capturing method based on a new multi-fluid incompressible Navier-Stokes formulation is developed. It is applied to a variety of free-surface flows including the Rayleigh-Taylor instability problem, the ship waves around a Wigley hull and a model bubble-rising problem to demonstrate the validity and versatility of the present method.
