Numerical Simulation of the Natural Convection in a Horizontal Bridgman Apparatus

Abstract

This work presents the numerical simulation of the natural convection with phase-change of succinonitrile (SCN) in a horizontal Bridgman apparatus. The analysis is carried out with two different numerical approaches: a thennally coupled temperature-based fmite element fonnulation for generalized phase-change problems and a finite volume discretization using an enthalpy-porosity technique to account for the latent heat effect. Both numerical results are compared with the experimental data obtained from the literature.
