The sloshing of liquids in low-gravity entails several technical challenges for spacecraft designers and operators. Those include the generation of significant attitude disturbances, the uncontrolled displacement of the center of mass of the vehicle or the production of gas bubbles, among others. Magnetic fields can be used to induce the reorientation of magnetically susceptible propellants and improve the controllability of a fluid system. Despite being proposed in the early 1960s, this approach remains largely unexplored. This paper provides new insight into the prospects and challenges of using magnetic control of space propellants. Key unanswered theoretical and technical questions are identified, highlighting the importance of developing appropriate analytical tools and fluid-magnetic simulation frameworks. New results associated with the reachability, scaling, long-term thermal and radiation stability, and efficiency of paramagnetic and ferromagnetic propellants are presented. Magnetic settling forces are shown to enhance the stability and speed up the oscillatory response of the liquid, leading to more predictable propellant management systems for different scales and filling ratios. These effects are particularly relevant for ferrofluids, whose enhanced magnetic properties make them excellent candidates for active sloshing control applications in space.

低重力下液体的晃动给航天器设计者和操作者带来了多项技术挑战。其中包括产生显着的姿态扰动、车辆质心不受控制的位移或气泡的产生等。磁场可用于诱导磁敏感推进剂的重新定向并提高流体系统的可控性。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。本文提供了对空间推进剂磁控制的前景和挑战的新见解。确定了未解决的关键理论和技术问题，突出了开发适当的分析工具和流体磁模拟框架的重要性。介绍了与顺磁和铁磁推进剂的可达性、缩放、长期热和辐射稳定性以及效率相关的新结果。磁性沉降力被证明可以增强稳定性并加速液体的振荡响应，从而为不同规模和填充率的推进剂管理系统带来更可预测的结果。这些效应与铁磁流体特别相关，其增强的磁性使它们成为空间主动晃荡控制应用的绝佳候选者。导致针对不同规模和填充率的更可预测的推进剂管理系统。这些效应与铁磁流体特别相关，其增强的磁性使它们成为空间主动晃荡控制应用的绝佳候选者。导致针对不同规模和填充率的更可预测的推进剂管理系统。这些效应与铁磁流体特别相关，其增强的磁性使它们成为空间主动晃荡控制应用的绝佳候选者。
