Freezing Heat Transfer Within a Water-Saturated Porous Media

Abstract

In the present study, analytical and experimental investigations were performed in order to clarify the characteristics of freezing heat transfer in a porous media saturated with water in a vertical rectangular cavity. In order to establish the momentum equation, the law of conservation of momentum was adapted for the fluid in our control volume and the equation took into account Forchheimer's extension as the resistance to flow in the porous media. Three different size glass, iron and copper beads were used as the porous medium in this study. The temperature of the cold wall was maintained at -10°C, while one of the hot wall was varied from 2°C to 22°C. comparisons of the analytical results with the experimental ones show good agreement with the exception of copper bead.
