Title

PHASE CHANGE MATERIALS for SPACECRAFT THERMAL MANAGEMENT.

Abstract

The results of an investigation to determine the capabilities of certain phase change materials (PCM) in pellet form to buffer heat loads immediately following short-term peak thermal input as part of a spacecraft thermal management system (SCTMS) are presented. It was found that two types of PCMs demonstrated potential for SCTMS: encapsulated inorganic salt hydrate (calcium chloride hexahydrate) and the form-stable crystalline polymer, radiation cross-linked high-density polyethylene. The PCM properties examined for the design of experimental packed bed heat exchangers included: packed bed porosity, mass density, pellet diameter, and melting point.
