Abstract

Liquid management is becoming increasingly essential as spacecraft carry more liquid, which includes liquid propellants. Interior corners are commonly used as components in spacecraft liquid management systems to passively position or maintain liquid. Under microgravity, the capillary flow along the curved interior corner plays a significant role in the behavior of liquids in spacecraft. To manage and transport liquids in space efficiently, it requires a full understanding of capillary flows in interior corners. In this work, the influence of corner angle on capillary flows in curved interior corners is studied experimentally. A series of drop tower experiments to simulate the microgravity environment are conducted to discuss the movement of liquid in the interior corner. Experimental results show that the liquid moves faster as the corner angle decreases. This feature can be utilized to design the liquid transport devices and provide valuable advices for liquid management in space.

角对毛细管沿弯曲内角上升的影响。
随着航天器携带的液体越来越多,其中包括液体推进剂,液体管理变得越来越重要。内角是航天器液体管理系统中常用的部件,用于被动定位或保持液体。在微重力条件下,沿弯曲内角的毛细流动对航天器内液体的行为起着重要的作用。为了有效地管理和运输空间中的液体,需要充分了解内部角落的毛细管流动。实验研究了弯角对弯曲内弯角毛细管流动的影响。通过一系列模拟微重力环境的落塔实验,探讨了液体在内角的运动。实验结果表明,随着转角的减小,液体运动速度加快。该特性可用于液体输送装置的设计,为空间液体管理提供有价值的建议。
