Abstract: A finite difference numerical method, based on the volume of the fluid (VOF) approach for tracking interface distortions, is presented. It is capable of accurately simulating the fluid flow of multiple immiscible fluids for metallurgical applications. This volume tracking method is based on piecewise linear reconstructions of interfaces, density distributions based on a shifted grid approach and a fully kernel-based CSF method for surface force modeling. Second order temporal and spatial accuracy are achieved using improved Euler time-stepping enhancement of a two-step project algorithm. Splash formation from a top submerged gas injection lance was simulated to illustrate the capability of the code in resolving the break up and fragmentation of liquid drops of possible use in the study of baths melting processes.
