On the Contact Heat Transfer with Melting : 2nd report: Analytical Study

Abstract

The melting phenomena of a solid, pressed on a surface with the temperature higher than the melting point, were analyzed and calculated numerically. The analytical results concerning non-dimensional heat flux agreed well with experimental results for water and octadecane shown in the former report. Then, an approximate formula relating non-dimensional heat flux with Stefan number and non-dimensional contact pressure was proposed. The liquid layer thickness distribution between the heat transfer surface and the melting solid, besides the distributions of pressure, velocity and temperature within the liquid layer, was also calculated and discussed.
