A numerical simulation of a horizontal Bridgman solidification process of a pure material in microgravity conditions is presented. The mathematical model here adopted describes the flow of the liquid phase, the heat transport phenomena within the whole sample and the evolution of the phase front. The stream-function/vorticity formulation of the liquid flow and the front-fixing treatment of the moving boundary are used. The numerical approximation is based upon a second order ENO (Essentially Non-Oscillatory) scheme combined with a second order time scheme. The validation of the mathematical and numerical model is provided in full gravity conditions versus physical experimental observations.
