| Guidelines |
| The dynamics of low-temperature fluids, such as superfluid Helium-4, is an open scientific problem. The experimental study of similarities and differences between quantum and classical flows is specifically an active research field, which already led to significant progress in our phenomenological understanding of the underlying physics. It also revealed that a comprehensive theoretical description is still missing, as, for example, in the case of the observed behaviour of moving bodies in quantum flows. The work aims then to propose mathematical models that can address open questions arising from the experimental analysis of cryogenic flows, especially those regarding the interactions between bodies and vortical structures, and assess their validity with relevant comparisons with suitable experimental data. |
