Simulation of double pipe heat exchanger with implementation of PCM

Abstract

In the present time several techniques have been developed in managing and storing thermal energy. Use of Thermal energy storage systems (TES) are one of the solutions for this issue. Hence in the present work, phase change materials (PCM) are used for storing thermal energy. D-mannitol and Hydroquinone are the two PCM materials used in double pipe heat exchanger and simulations are carried out analytically on ANSYS. Study of temperature variation is done with respect to time and values are calculated for time, t = 200, 500, 2200 and 4200 seconds. The results also include contour plots and numerical values for mass fraction for each of the case. The result shows, that with increase in the time step, the temperature gradually increases for both the cases of PCM materials.
