Abstract
A combined numerical and experimental study is reported of solid/liquid phase change in porous media with natural convection in the melt region. The model is based on volume averaged transport equations, while phase change is assumed to occur over a small temperature range. Experiments are performed in a vertical, square enclosure using gallium and glass beads as the fluid and the porous matrix, respectively. For natural convection, melting and solidification (with initial supercooling), the numerical results show reasonable agreement with the temperature and interface position measurements. Natural convection in the melt as well as heat conduction in the solid is found to considerably influence the interface shape and movement during both the melting and solidification experiments.
