ABSTRACT

A metal porous block is available to disturb fluid flow and enlarge heat transfer surface which enhances heat transfer rate. In order to reveal a behavior near a heat transfer surface between a porous media and a impermeable heated wall, a flow and thermal field of porous media with phase change, on which high heat load is imposed, is investigated numerically using the two-phase mixture model. A numerical method of SIMPLE is adopted to solve governing equations. Numerical results for the temperature fields and the flow fields of the two-phase mixture and the individual phases are presented and discussed.
