Abstract

Experiments are reported on the study of the effect of natural convection on the controlled solidification of lead under conditions of nearly unidirectional heat flow within the system. The experimentally found shape and position of the solid-melt interface was reasonably well predicted by the consideration of heat transfer by natural convection from the melt to the solid surface. Transient runs were also carried out and here the rate of movement of the melt-solid interface was readily predicted from the (numerical) solution of the appropriate unsteady state conduction equation.
