Thermal characteristics on melting/solidification of low temperature PCM balls packed bed with air charging/discharging

Melting and solidification phenomena of low-temperature phase change material (PCM) balls packed bed with air flowing during charging and discharging were tested and modeled by numerical enthalpy method. In this study, a commercial paraffin RT-42 (melting point 38°C-43 °C) contained in a set of cell...
