Abstract

Propellant tanks provide non-entrained propellant for thrusters of satellites, which plays an important role in space mission. And the fluid transfer efficiency of tanks is the key to supply non-entrained propellant. An experiment cabin containing two different scaled tank models are designed and experiments of liquid reorientation under microgravity are carried out in the Chinese Space Station. Experiment results present the high liquid transportation efficiency of the two kinds of propellant management devices. Finite element models of the two tank models are established and verified by simulation matching with experiments. Furthermore, methylhydrazine is adopted to carry out more simulation analysis by considering different liquid contact angles and surface tension, and numerical results show smaller liquid contact angle and bigger surface tension can increase liquid flow speed. This research can provide theory and data support for the design of plate type tanks.

中国空间站储罐模型充气过程中的液体爬升行为研究

推进剂贮箱为卫星的推进器提供非内燃推进剂，在太空任务中发挥着重要作用。而贮箱的流体传输效率是提供非内含推进剂的关键。我们设计了一个包含两个不同比例贮箱模型的实验舱，并在中国空间站进行了微重力条件下的液体重新定向实验。实验结果表明，两种推进剂管理装置的液体输送效率都很高。建立了两种贮箱模型的有限元模型，并与实验进行了仿真验证。此外，采用甲基肼进行了更多的仿真分析，考虑了不同的液体接触角和表面张力，数值结果表明较小的液体接触角和较大的表面张力可以提高液体流动速度。该研究可为板式储罐的设计提供理论和数据支持。

期刊介绍： Microgravity Science and Technology – An International Journal for Microgravity and Space Exploration Related Research is a is a peer-reviewed scientific journal concerned with all topics, experimental as well as theoretical, related to research carried out under conditions of altered gravity. Microgravity Science and Technology publishes papers dealing with studies performed on and prepared for platforms that provide real microgravity conditions (such as drop towers, parabolic flights, sounding rockets, reentry capsules and orbiting platforms), and on ground-based facilities aiming to simulate microgravity conditions on earth (such as levitrons, clinostats, random positioning machines, bed rest facilities, and micro-scale or neutral buoyancy facilities) or providing artificial gravity conditions (such as centrifuges). Data from preparatory tests, hardware and instrumentation developments, lessons learnt as well as theoretical gravity-related considerations are welcome. Included science disciplines with gravity-related topics are: − materials science − fluid mechanics − process engineering − physics − chemistry − heat and mass transfer − gravitational biology − radiation biology − exobiology and astrobiology − human physiology
