The effect of thermal cyclic variation on the thermophysical property degradation of paraffin as a phase changing energy storage material

Thermophysical properties of phase change material (PCM) and their thermal stability over their lifetime are necessary to be understood to build an efficient latent heat storage system. This study aims to investigate the degradation in thermophysical properties of a phase change material (paraffin w...
