Ice Melting Heat Transfer in a Horizontal Elliptical Tube Immersed in Water—Effect of Ambient Temperature and Oriented Angle—

Abstract

The characteristics of ice melting heat transfer in a horizontal elliptical tube immersed in water are studied experimentally and numerically. This phenomenon is caused by a combination of the natural convection heat transfer of water around the tube and ice melting heat transfer inside the tube. This combined heat transfer process has been studied numerically. A large number of studies on melting heat transfer in a simple shape capsule has been done; however, study of melting heat transfer in a horizontal elliptical tube are few. Ice melting characteristics, temperature profiles, flow patterns, average Nusselt number profiles, and ice melting rate are shown.
