Abstract
Melting of ice in a rectangular enclosure is studied. The ice cube is subjected to a constant temperature higher than its melting point at the upper boundary and maintained at its melting point at the lower boundary. All other boundaries are insulated. Liquid water starts forming near hot region as temperatures reach above the melting point of ice. This phenomenon is modeled by unsteady heat transfer in liquid and solid phases. The solution is carried out in two different ways. First, the liquid is assumed to be still. In this case, both phases experience only conductive type of heat transfer. The same system is also modeled by assuming the liquid to be a mixed body subjected to natural convection from the top hot surface and the phase front. The flux at the phase front is obtained by finding a heat transfer coefficient for natural convection with a cold plate facing upward. Results of the numerical model including natural convection in a simplified way shows good agreement with the preliminary experimental work.
