Abstract

Abstract Melting of a vertical ice layer immersed in immiscible liquid has been investigated experimentally to determine the interaction of melt flow based on ice melting and free convection induced by buoyancy in the liquid. Oil, which was contained in a rectangular vessel, was utilized as a testing liquid. During the melting process the solid-liquid interface behavior as well as the ambient liquid flow patterns were extensively observed. Three distinct flow regimes were identified for the ambient liquid temperatures of 7.6 to 30.0°C covered. Photographs of flow regimes are presented, and dependence of the flow structure on the melting morphology is discussed. The local/average heat transfer coefficient at the melting interface and the melt fraction were determined as a function of the ambient liquid temperature as well as melting time.
