|Abstract: ||Abstract: Gallium melting in a rectangular cavity heated from the side has been studied experimentally  and numerically [2-4]. However, their findings are not consistent, such as, disagreement between numerics and experiments, the myth of grid-converged solution, is the multicellar solution physically correct?, etc. We re-examine this problem with the thermally driven mushy cell tracking method [5, 6]. In the method, computational domain is separated into solid-phase region and liquid-phase region, with the mushy cells in between. The thermo-fluid field is expressed in terms of primitive variables and discretized on the fixed grid with the finite-volume formulation, and solved by the SIMPLE algorithm.The interface tracking equation is based on the mass and energy balance to predict the movement of mushy cells. Prediction of the moving interface and thermo-fluid field of Gallium melting agrees well with the experiment data  and other numerical solutions [2-4].|
