中文摘要:针对天基红外凝视与扫描观测系统的 载荷冷却需求,具有流体传输和热传输能力 强、扬程大以及可调节性较强等优点的泵流体回路可用作长距 离、大面阵、分布性载荷的冷却回路。在单相流体回路中,对 气相分数的控制非常重要。介绍了一种基于多孔介质 中两相流体的流动机理实现气液两相分离的装置及其设计思路和试 验验证方法。通过数值计算及仿真得到了优化参数,测量 了回路中的流动参数,并验证了此装置的气液分离效果。

Experimental Investigation of Liquid-gas Separation Based on Single Phase Pump Driving Circuit
Abstract:In the light of the payload cooling requirements of space-based infrared staring and scanning observation systems, pump driving circuits having advantages of strong fluid and heat transferring, high-lift and high adjustability can be used as the cooling circuits for long distance large area array distribution payloads. It is very important to control the gas void fraction in a single phase liquid circuit. A gas-liquid separation device based on the flow mechanism of two phase fluid in a porous zone is designed. Its design ideas and test verification are presented. Optimized parameters are obtained through numerical calculation and simulation. Flow parameters are measured. The gas-liquid separation effectiveness of this device is verified.
