Effect of Density Change on Rapid Liquid-Solid Interface Kinetics and Heat Flow

Abstract

ABSTRACTConsequences of the need to transport density to or from a fast-moving liquid-solid interface are examined. There can be a severe limitation of the freezing velocity and a change in the amount of heat which must be conducted. The latter effect produces a net latent heat which can be significantly different from the equilibrium value and even change sign.
