单相流体回路工质的试验研究

介绍了单相流体回路设计中流体工质的基本性能参数与选择标准,还介绍了流体回路试验平台;比较了"神舟"飞船流体工质和混合物Secool-3工质的物理特性参数,并进行了室温工况和低温工况试验,试验结果表明Secool-3工质应用于单相流体回路具有较好的系统性能。

Experimental Research of Working Fluid Used in Single-Phase Fluid Loop System

Selecting working fluid is an important content of designing single-phase fluid loop system.The chief parameters and criterions for selecting working fluid were considered.The test platform of single-phase fluid loop system was introduced.Based on comparing the chief parameters between the fluid used for Shen Zhou spacecraft and Secool-3 which is one kind of mixture,the experiments at room temperature and low temperature were carried on.The result of the experiments indicates that the single-phase fluid loop system has good performance when Secool-3 mixture is applied.
