Study on Combined Latent- and Sensible-Heat Thermal Energy Storage : Optimization of Unit in Relation with Operating Conditions : Heat Transfer, Power, Combustion, Thermophysical Properties

Abstract

In order to pursue the high performance of thermal energy storage, a combined type of latent-and sensible-heat thermal energy storage (TES) system is proposed, and its performance is investigated experimentally and theoretically. The theoretical treatment is made taking in account the recirculating flow in the capsule. In comparison with the theoretical answers and the experimental results given by preceding report, the optimum design of TES is determined in relation to the operating conditions and Phase Change Material (PCM).
