普罗米修斯项目空间核电站选择的配置是通过气体冷却剂/工作流体将布雷顿能量转换回路直接耦合到单个反应堆热源。假设氦（He）和氙（Xe）气体的混合物为冷却剂/工作流体。氦气具有优越的导热性，而氙的加入是为了增加气体的原子量，有利于涡轮机械的设计。这两种元素都具有非反应性的优点。HeXe输运性质（粘度和导热性）需要计算压降和传热率。HeXe混合物的数据是有限的，需要使用半经验相关性来计算混合物的性质。有几种方法可用。在混合计算中，通常需要纯组分的性质。虽然分析方法可用于估计纯组分的性质，但充分的氦和氙纯组分数据是可用的。本文比较了纯钴的来源。
The selected configuration for the Project Prometheus Space Nuclear Power Plant was a direct coupling of Brayton energy conversion loop(s) to a single reactor heat source through the gas coolant/working fluid. A mixture of helium (He) and xenon (Xe) gas was assumed as the coolant/working fluid. Helium has superior thermal conductivity while xenon is added to increase the gas atomic weight to benefit turbomachinery design. Both elements have the advantage of being non‐reactive. HeXe transport properties (viscosity and thermal conductivity) were needed to calculate pressure drops and heat transfer rates. HeXe mixture data are limited, necessitating the use of semi‐empirical correlations to calculate mixture properties. Several approaches are available. Pure component properties are generally required in the mixture calculations. While analytical methods are available to estimate pure component properties, adequate helium and xenon pure component data are available. This paper compares the sources of pure co...
