ABSTRACT
In this paper, the unsteady state heat transfer through the thermal energy storage system is investigated numerically by using finite difference method in order to study the optimum thermal design of the latent heat thermal storage. The present analysis takes into account the heat transfer in two dimensions for fluid, tube and the PCM. The conical shape of the PCM is examined here for different diameters depending on the cone angle (?). The results of the present study are compared with other study to confirm the accuracy. Results of a numerical case study are presented and discussed. The results show that the decreasing the value of (?) will increase the hot and cold fluids effectivenesses and the difference between the effectiveness (hot and parallel cold and counter cold) increased with decreased value of (?) in the negative range (? = -0.13 deg). The counter flow for the cold fluid produce higher effectiveness than the parallel flow for the cold fluid especially for the negative value of (? = - 0.13 - 0 deg).
