Development of nontoxic heat transport fluids for habitat two-phase thermal control systemsA computational chemistry approach based on pattern recognition techniques is used to correlate molecules thermodynamic and chemical properties with its molecular structure. The potential to develop a suitable two-phase nontoxic heat transport working fluid for the spacecraft habitat environment is discussed. It is concluded that the perfluorocarbons represent a potentially useful class to consider as a source of the working fluids because of their low toxicity, thermal stability, and chemical inertness. The ADAPT software program is considered to be adequate to make structural and property predictions.
