Summary

AN ANALYSIS IS CARRIED OUT FOR THE SOLIDIFICATION IN A RECTANGULAR ENCLOSURE WHOSE TOP AND BOTTOM SURFACES ARE KEPT ADIABATIC AND SIDES ARE KEPT AT A CONSTANT TEMPERATURE. THE TRANSIENT EFFECTS OF SOLIDIFICATION ACCOMPANIED BY NATURAL CONVECTION HAVE BEEN STUDIED IN DETAIL. THE GOVERNING EQUATIONS ARE WRITTEN FOR THE TEMPERATURE, VORTICITY, STREAM FUNCTION AND VELOCITY IN THE MELT ALONG WITH THE HEAT CONDUCTION EQUATIONS THROUGH THE SOLID AND THE MOLD. THE NON-LINEAR COUPLED EQUATIONS HAVE BEEN NON-DIMENSIONALIZED AND SOLVED WITH THE AID OF THE ALTERNATING DIRECTION IMPLICIT FINITE DIFFERENCE METHOD. THE VELOCITY PROFILES IN THE MELT, AND THE TEMPERATURE DISTRIBUTION IN THE MELT, THE SOLID AND THE MOLD ARE SHOWN.
