The melting process of ice is computationally examined. In this study, an ice (solid phase) is modeled by a very high viscous fluid and three-component immiscible liquid flows with surface tension are solved. The Moment-of-Fluid (MOF) method, is used to track the evolution of multiple interfaces. The numerical simulations are carried out by solving the conservation law equations for mass, momentum, and energy. The melting process of an ice with a cylindrical form is considered. From numerical results, it is shown that the melting process of ice can be successfully reproduced: the ice begins to melt at t > 0 and the solid phase near the heated plate changes into the liquid phase (water). The liquid phase flows and spreads in a radial direction with time. Finally, the solid phase fully changes into the liquid phase and the liquid phase widely covers the heated plate. As for temperature fields, higher temperature fields are formed in the region of gas and liquid phases and the cold temperature fields are maintained neat the solid phase. The effect of contact angle on the melting process is also presented.
