Numerical and Experimental Investigation for Heat Transfer in Triplex Concentric Tube with Phase Change Material
A numerical and experimental investigation of a thermal energy storage unit which involves phase change process dominated by heat conduction is presented. The thermal energy storage unit involves a triplex concentric tube with phase change material (PCM) filling in the middle channel. The hot heat transfer fluid ( HHTF) flows in outer channel during charging process and the cold heat transfer fluid (CHTF) flows in inner channel during discharging process. A simple numerical method has been developed for the analysis of PCM solidification in the triplex concentric tube. An experimental apparatus has been built by which the effect of the inlet temperature and the flow rate of CHTF on the thermal energy release has been studied.
