Solid/liquid phase-change heat transfer in porous media has been extensively studied in the past several years, and effects of various parameters on the heat transfer have been clarified. In such systems, the heat transfer coefficient is usually very small due to a small thermal conductivity in the systems and a large resistance to the fluid flow due to a porous matrix. Therefore, some means for heat transfer enhancement is needed for the systems. The use of conducting plates (or fins) may be considered quite reliable and effective for this purpose. As far as the authors could determine, no numerical studies appear to have been reported on the melting process around a hot surface with the conducting plates. In the present study, numerical calculations have been performed using an enthalpy method for melting processes around a hot wall with/without conducting plates. These results have been compared with experimental ones.
