The use of alternative fuels for future aerial or naval mobility poses several challenges, particularly for liquid fuels such as cryogenic hydrogen. When stored in reservoirs and subjected to external excitation, they experience sloshing, the movement of the free surface. This phenomenon is particularly critical from both an inertial perspective, as forces are exerted on the tank walls, and from a thermodynamic perspective, as cryogenic liquids suffer phase changes, leading to fluctuations in gas pressure inside the tank. Investigating these phenomena and understanding their underlying dynamics is essential for developing diagnostic tools and creating a digital twin, enabling control techniques to be implemented to manage these fluctuations and optimize them for our purposes.
