Thermal state-of-charge in solar heat receivers [PDF]

36th AIAA Aerospace Sciences Meeting and Exhibit, 1998
A theoretical framework is developed to determine the so-called thermal state-of-charge (SOC) in solar heat receivers employing encapsulated phase change materials (PCMS) that undergo cyclic melting and freezing. The present problem is relevant to space solar dynamic power systems that would typically operate in low-Earth-orbit (LEO).
