Numerical and Experimental Study on Melting Heat Transfer of Liquid Ice in a Rectangular Cavity
ABSTRAKT
The melting characteristics of liquid ice in a rectangular cavity was studied numerically and experimentally. The liquid ice, mixture of ice particles and ethylene-glycol aqueous solution, was heated from one of the vertical walls of the cavity. The shape of the mush-liquid interface, melting rate, and local/mean heat-transfer coefficient at the heated vertical wall were observed, measured, and calculated under a variety of conditions of heat flux and initial concentration of aqueous binary solution. It was found that the formation of double-diffusive layers based on the thermal and solutal buoyancy forces exerted a great influence on the melting process of the liquid ice.
