Numerical heat transfer study of energy storage materials used in the latent heat storage system
This paper deals with the theoretical investigation of the two phase change materials (PCMs) that can be used as a latent heat storage (LHS) media. The two PCMs chosen were composed of fatty acids i.e. capric acid (CA), lauric acid (LA), and myristic acid (MA) having weight composition CA-LA-MA (30/35/35 wt.%) (CLM355) and CA-LA-MA (40/30/30 wt.%) (CLM433). The calculations were made on the melt fraction considering the conduction only with a two-dimensional simulation approach based on enthalpy. The different container materials that were chosen for undertaking this work include glass, tin, stainless steel (SS), aluminum, aluminum mixed (AM), and copper. The result showed that lower thermal conductivities values of the container material made a significant contribution to the melt fraction rather than the higher ones. Out of the two PCMs, CLM355 showed better compatibility with the container materials. The initial temperature of the PCM kept on the container does not influence its melting rate. The outer wall temperature affects the melt fraction that increases with an increase in the temperature difference between the outer wall and the melting temperature of the PCM. It has also been observed that the melting rate is independent of the thickness of the container material.
