On the change of phase when both the phases have different thermal properties

Abstract

The growth of a plane boundary advancing in the supercooled fluid is discussed. The assumption of difference in densities results in a connective motion of the fluid and the mass solidified per unit area per unit time will occupy, on solidification, a different volume from that originally occupied by the fluid. The effect of finite conductivity of the solid on the growth has been studied by taking the Prandtl number different from unity. It is shown that equivalence of interface temperature and surface temperature of the solid leads to the results discussed by Chambre (1).
