要約

A second-law analysis is conducted on the cyclic behaviour of a Latent Heat Thermal Storage Module (LHTSM) in which the heat charge and removal are both performed by flowing streams of fluids. Attention is focused on power production applications, where stability of the heat supply as well as of the operating temperatures is a main concern. The majority of publications concerned with this subject consider minimum entropy generation a basic design criterium. In the present paper this approach is discussed and criticized: a numerical study suggests the conditions for an efficient design and operation of the storage system.
