Research Abstract |
We derived equations to estimate the temporal change in the amount of stored heat in phase change material (PCM) that exchange heat with flowing water. There are two types of PCM concerning the range of the phase-change temperature. One has the range, and the other doesn't have the range. We derived the equations for the both types of the PCM. No rigorous analysis has been carried out for these cases. Therefore, we considered methods to obtain approximate solutions based on a number of approximations. By visualizing the approximate analytical results and comparing them with the numerical simulation results, we checked the applicability of the approximate analytical results as the equations to estimate the temporal change in the amount of stored heat in the PCM.
