The Effect of an Electric-Field on Heat and Mass-Transfer for Dielectric Crystallization
This paper describes the effect of an electric field on heat and mass transfer for dielectric crystallization. A theoretical analysis was carried out to obtain the heat and mass transfer for crystal growth and the electric force effect on heat and mass transfer. Basic expressions for the force and for the relation of temperature and electric field were derived. Meanwhile, the effect of an electric held on crystallization is predicted. Experimental work has also been carried out by applying zero and 15kV d.c., in turn, to a dielectric sample melt. The results show good agreement with theoretical predictions.
