| Research Abstract |
Effective thermal energy storage is essential for effective use of solar heat, industrial waste heat, and urban waste heat. Latent heat thermal energy storage uses the characteristic that materials release heat during the change from liquid to solid. This work aims at control of nucleating temperatures of materials by controlling wettability. The influences of insoluble particles in the melt of several kinds of representative phase change materials (PCMs), mass of the PCMs that are filled up in storage capsules, and contact angles of the PCMs on the capsules, on the maximum degree of supercooling were investigated. From the experiments, control effect of wettability on the starting temperature of solidification was evaluated.
