Abstract�� Performance studies of a phase change thermal storage/radiation heat sink for extravehicular activity have been undertaken by experimental investigation and numerical simulation. The test specimens of phase change thermal storage were designed and the cooling tests of phase change thermal storage were conducted. The mathematical model of phase change thermal storage with coupled convection and conduction boundary conditions has been established. The effects of convective heat transfer and voids are considered in this model. A computational program has been developed for evaluating the performance of phase change thermal storage. The reliability of the program has been verified based on the experimental results. This program is a useful analysis tool for the design and optimization for a phase change thermal storage.
