Thermal Management of the Melting Process in a Latent Heat Triplex Tube Storage System Using Different Configurations of Frustum Tubes

In this study, the energy charging mechanism is mathematically modeled to determine impact of design modifications on thermofluidic behavior a phase change material (PCM) filled in triplex tube containment geometry. The surface area middle tube, where PCM placed, supported by single or multi-internal frustum tubes vertical increase performance heating and cooling system. addition ordinary straight tubes, three more scenarios are considered: (1) changing (2) inner (3) both internal central tubes. adopting designs gap width were studied. outcomes reveal that heat storage rates increased for all systems compared According results, case 5 mm optimal one among studied cases terms melting time rate. Employing configuration with 5-mm would save 25.6% rate 32.8% base
