Numerical Analysis of Phase Change Material (SiC \({\mathrm{H}}_{3}\) ) Used for Energy Storage

The high energy storage density of Phase Change materials is one of the primary reason for their widespread application in the energy storage due to its constant phase change temperature. In this paper analysis of PCM has been shown using ANSYS Fluent software. Here, the PCM has been used for the analysis is Methyl-Silylidine (SiC \({\mathrm{H}}_{3})\) . Here, in this paper the analysis has done in cylindrical model as in future it can be used for energy storage unit model. The outer pipe is declared with 511 K temperature due to which the PCM inside the annular region will melt and when it solidifies the heat is being released which is carried out by the water flowing inside the inner pipe. For first 100 s the value of liquid fraction was taken which was 0.690 and similarly up to 600 s the data was taken and the decrement in the liquid fraction was observed due to the increment in temperature. Also the outlet temperature for the PCM material was taken starting from 100 to 600 s and the decrement in the temperature was observed which indicates that when the phase change material melts and solidifies, it releases heat. A good number of research has been done and still going on the Phase Change Material which is being widely used for energy storage. Due to the energy crisis in the day to day life, it has been a concern and also motivated researchers to do research on different Phase Change Material (PCM) which are being widely used for the energy storage systems.
