“…A rare exception is the NASA Magnetically Actuated Propellant Orientation (MAPO) experiment, that studied the magnetic positioning of liquid oxygen and validated a custom CFD model with a series of parabolic flight experiments with ferrofluids [31]. Subsequent publications presented numerical models to study and generalize the measurements for space applications [32][33][34].…”

The sloshing of liquids in microgravity is a relevant problem of applied mechanics with important implications for spacecraft design. A magnetic settling force may be used to avoid the highly non-linear dynamics that characterize these systems. However, this approach is still largely unexplored. This paper presents a quasi-analytical low-gravity sloshing model for magnetic liquids under the action of external inhomogeneous magnetic fields. The problems of free and forced oscillations are solved for axisymmetric geometries and loads by employing a linearized formulation. The model may be of particular interest for the development of magnetic sloshing damping devices in space, whose behavior can be easily predicted and quantified with standard mechanical analogies.

“…This is an important parameter for space applications due to its capacity to establish an upper disturbance limit and drive the design of the liquid management system [2,3]. The dependence of * with the filling ratio [19], of the reorientation time with , and of the critical Bond number with were explored for the NASA MAPO tank by Marchetta and coworkers [20,21]. Subsequent models extend the computational setup to non-linearly magnetized materials and complex geometries [25].…”

“…Such ferrofluids were selected to approximate the linear magnetization curve of liquid oxygen for different magnetic field intensities. Subsequent publications presented refined numerical models and numerical results of technical relevance [17][18][19][20][21][22][23][24][25]. The axisymmetric and lateral sloshing of water-based ferrofluids was characterized in microgravity when subjected to an inhomogeneous magnetic field as part of the ESA Drop Your Thesis!…”
