The sloshing of liquids in low-gravity entails several technical challenges for spacecraft designers due to its effects on the dynamics and operation of space vehicles. Magnetic settling forces may be employed to position a susceptible liquid and address these issues. Although proposed in the early 1960s, this approach remains largely unexplored. In this paper, the equilibrium meniscus and axisymmetric oscillations of a ferrofluid solution in a cylindrical tank are studied for the first time while subject to a static inhomogeneous magnetic field in microgravity. Coupled fluid-magnetic simulations from a recently developed inviscid magnetic sloshing model are compared with measurements collected at ZARM’s drop tower during the ESA Drop Your Thesis! 2017 campaign. The importance of the fluid-magnetic interaction is explored by means of an alternative uncoupled framework for diluted magnetic solutions. The coupled model shows a better agreement with experimental results in the determination of the magnetic deformation trend of the meniscus, but the uncoupled framework gives a better prediction of the magnetic frequency response which finds no theoretical justification. Although larger datasets are required to perform a robust point-by-point validation, these results hint at the existence of unmodeled physical effects in the system.

由于液体在低重力下的晃动会对航天器的动力学和运行产生影响，因此它给航天器设计人员带来了多项技术挑战。可采用磁沉降力来定位敏感液体并解决这些问题。尽管在 1960 年代初就提出了这种方法，但这种方法在很大程度上仍未得到探索。本文首次研究了在微重力条件下受静态非均匀磁场作用时圆柱罐中铁磁流体溶液的平衡弯液面和轴对称振荡。来自最近开发的无粘性磁晃荡模型的耦合液磁模拟与在 ESA Drop Your Thesis期间在 ZARM 的落塔收集的测量值进行了比较！2017 年竞选活动。通过用于稀磁溶液的替代非耦合框架探索了流体-磁相互作用的重要性。在确定弯月面的磁变形趋势时，耦合模型与实验结果显示出更好的一致性，但非耦合框架对磁频率响应进行了更好的预测，但没有任何理论依据。尽管需要更大的数据集来执行稳健的逐点验证，但这些结果暗示系统中存在未建模的物理效应。
