117 Heat Transfer Enhancement for Thermal Energy Storage Using Metal Foams Embedded within Phase Change Materials (PCMS)
Download citation file:
In this study the experimental investigation on the solid-liquid phase change (melting and solidification) processes have been carried out. One kind of paraffin wax is used as the PCM, in which metal foams are embedded to enhance the heat transfer. During the melting process, the test samples are electrically heated on the bottom surfaces with a constant heat flux. The PCM with metal foams has been heated from solid state to pure liquid phase. The temperature differences between the heated wall and PCM have been analysed to examine the effects of heat flux and metal-foam structure (pore size and relative...
