Abstract
Infiltration by a pure liquid metal into a rigid preform in the presence of partial solidification is analyzed. The mathematical model which is developed takes into account the coupling between the flow through the porous medium and the thermal effects. The model has a two-scale formulation: phase change occurs at the microscopic scale, while macroscopic flow and heat transfer involve large scale quantities.
