Abstract
The melting process of phase change material (PCM) for thermal energy storage purposes has been studied and simulated in this paper. Using the ANSYS (Fluent) 2023 R1 software, the melting of a rectangular PCM zone with left and right sides exposed to convection heat and the other sides adiabatic is simulated. The study also discusses the program specifications, numerical modeling equations, and assumptions. For a total melting duration of 360 min, the contours of the liquid fraction, temperature, density, and velocity of phase change material particles are shown at regular intervals of 30 min. The contours aid in identifying how the melting interface changes in shape and motion as melting time increases. It also describes how the melting fraction changes over time, which provides information regarding the amount of melted PCM at various points.
