| ABSTRACT : |
The thermal energy storage is considered to be one of the energy storage technologies. Thermal energy storage contains a thermal storage mass, and can store heat or cool. Basically, it can be classified as latent, sensible and thermo-chemical energy. Among these energy storage types, the most attractive form is latent heat storage in phase change material (PCM) because of the high storage capacity in a small volume and charging and discharging heat from the system at nearly constant temperature. In this project the heat transfer between the therminol oil and encapsulated PCM in various layers is analyzed using Computational Fluid Dynamics.
The PCM tank contains 3 layers of mesh structure in which spherical encapsulation are fixed. It is designed using ANSYS and the heat transfer between the heat transfer fluid and the various layers of encapsulation is analysed. During the charging mode the temperature of the therminol oil is given as 500°C as a input and the heat transferred to the various layers of the encapsulation is found using CFD. Similarly during the discharge mode the temperature of the therminol oil is noted taking PCM temperature as an input.
