Abstract

Thermal cycling tests were performed to determine the phase change temperature shift of pure barium hydroxide octahydrate (Ba(OH)₂·8H₂O) phase change material (PCM) with respect to 150 accelerated thermal cycles. The results show a slightly phase change temperature shift and a severe supercooling phenomenon with the increasing number of thermal cycles. The compatibility of Ba(OH)₂·8H₂O with the PCM containing materials like aluminum alloy and copper was also studied by using scanning electron microscope (SEM) after 50 thermal cycles. Ba(OH)₂·8H₂O was a stable PCM with good compatibility with copper as a containing material. An experimental setup was built to study the heat transfer performances of Ba(OH)₂·8H₂O with/without copper foams. The contrast experiments conclude that high porosity metal foams not only significantly enhance the heat transfer rate of PCMs, but also effectively reduce the supercooling degree of Ba(OH)₂·8H₂O.
