Abstract
This paper is concerned with the melting of a vertical ice plate into a calcium chloride aqueous solution inside a square cavity. The initial temperatures of the ice and the liquid are −5°C and 0°C respectively, and the initial solute (i.e. CaCl2) concentration of the liquid is 20wt% at the beginning of melting. The ice melts spontaneously with decreasing temperature in the melting system. This typical melting behavior is mainly attributed to the combined effects of the driving forces of diffusion of solute(CaCl2)/solvent(H2O), and also heat transfer near the melting front. A complicated double diffusive convection in the liquid layer affects the melting rate of the ice. It is seen that the numerical results, including some assumptions in the melting-front-control volume of the continuum model [15,
