Abstract

Several researchers have been engaged in three-dimensional (3-D), mathematical modeling of melt flow in tundishes using finite difference techniques over the past 10 to 15 years. Most of these computational schemes employ thek-ε model of turbulence and are capable of predicting the general flow pattern in different flow systems. However, detailed comparison of computed results with water-model experiments in the tundish system has shown that the finite difference grid spacing has an influence on the predicted fluid flow and the residence time distribution of the melt. In the present work, the effect of variation in the grid spacing on the flow predictions is presented. Further, guidelines are presented for proper spacing of grids to enhance the predictive capabilities of such models.
