Introduction

Many physical phenomena of importance in engineering and environmental applications involve immiscible fluids separated by a well defined interface denoted as free-surface flows.  Examples include filling of fluid in metal casting operations, polymer injection molding, flow of air pollutants around industrial plants, etc.. .  In these problems there is no inter-phase mass transfer, and generally the fluid are distinct in their composition.  The simulation of such physical phenomena is important in many respects: for metal casting and polymer injection molding the final quality of the product is highly dependent on the type of flow circulation occurring within the cast of mould, changing the casting design to minimize turbulent flow for example can drastically minimize void defects in the product.

Work on the development of a robust Free-Surface Flow algorithm was initiated with an LNCSR initiation fund, the work was completed in September of 2003,  Work is currently focused on ithe development of an improved VOF advection scheme , STACS.
