Computational Modeling of Heat and Mass Transport and Control of Solid/Liquid Transition Systems

Abstract

This paper deals with a review of numerical investigations of solid/liquid phase change configurations obtained by using an enthalpy-porosity formulation coupled to a finite volumes approximation. Attention is focused on the control of convective motion in the liquid phase using operating parameters as growth rate and thermal gradient of the furnace. Situations involving thermal convection holding in the earth and in the microgravity environment are discussed. Control using constant magnetic field is illustrated.
