Simulation Investigation for Heat Transfer in Fin-Tube Thermal Storage Unit with Phase Change Material

Abstract:

This paper addresses a simulation investigation of a fin-tube thermal storage unit involving phase change process dominated by heat conduction. The heat transfer of fin-tube thermal storage unit with phase change material (PCM) was simulated by Fluent. Graphical results including outlet temperature of heat transfer fluid (HTF), average temperature of PCM and phase front interface of solid and liquid phase of PCM versus time and fin distance were presented and discussed. According to simulation results, it was concluded that only the fin-tube thermal storage unit with fin distance of 12fin/inch could satisfied the request of heat release performance of household heat pump water heater for shower.
