Abstract Most phase change materials employed in latent heat thermal energy storage suffer from poor thermal conductivity both in liquid and solid phases, leading to low heat transfer effectiveness. To overcome this limitation, multiple PCMs and gradient copper foam have been used to accelerate the melting of phase change materials and improve the heat transfer effectiveness. The heat transfer performance of shell-and-tube thermal energy storage unit consisting of radial multiple PCMs and singl...

Abstract This paper reviews cascaded or multiple phase change materials (PCMs) approach to provide a fundamental understanding of their thermal behaviors, the performance in terms of heat transfer uniformity, and the influence of input parameters and different geometrical containments on the performance of latent heat thermal energy storage (LHTES) systems. Furthermore, the performance enhancement of energy components through the implementation of cascaded techniques and cascaded arrangements o...
