摘要：
Thermal energy storage based on phase changes is a promising technology. However, heat transfer can often be problematic. A latent heat storage based on the single tube design is analyzed in a computer tomograph. The different densities of the solid and liquid phase change material (PCM) MgCl(2)6H(2)O enable a clear identification of the phases in the computer tomographic images. No supercooling or phase segregation of water from the PCM was observed during melting or crystallization. The volume change, though often neglected, seems to be the biggest issue of the design of latent heat storage systems.
