This article proposes a computational and mathematical study to analyse interface position, rate of interface and temperature variation of encapsulated phase change thermal energy storage system (TESS) with constant heat flux for outward melting process. Conduction is the main phenomenon that governs the melting process. Spherical and cylindrical geometry is used to encapsulate the phase change material to avoid direct contact between heat transfer fluid (HTF) and phase change materials, which is under constant temperature boundary condition, applied only on one wall. Other walls are thermally insulated. The computational results are obtained for melting of solid which is initially at its fusion temperature by using computational fluid dynamics software and a matlab code has been written to develop a mathematical model for this study.
