Abstract�� To improve the void distribution and thermal performance of phase change thermal storage devices, thermal storage containers embedded with nickel foam cores were designed and manufactured based on the theoretical research. Phase change experiments were carried out with those containers, as well as containers without nickel foam, and the temperature variations of containers were tested and saved using platinum resistance thermocouples (Pt100) and data acquisition modules (ADAM-4000). Void distributions of those containers were imaged by the computed tomography (CT) instrument after the experiments. The results of two kinds of containers were compared with each other, and the improvements of embedding nickel foam were testified both in void distribution and thermal performance of solid-liquid phase change process. The research findings could provide some values for the application of solid-liquid phase change thermal storage.
