| Guidelines |
| The dynamics of low-temperature fluids, such as superfluid Helium-4, is an active research field. Progress in our phenomenological understanding of the underlying physics has been achieved in recent years by employing flow visualization techniques that allows following the motion of small particles suspended in the fluid. The work focuses on the experimental analysis by visualization of the particle dynamics in the proximity of a cylinder of rectangular cross section oscillating in liquid Helium-4. Its aim is to investigate the occurrence of macroscopic vortical structures in cryogenic flows, as their nature is still not entirely understood, and therefore analyse similarities and differences between classical and quantum flows. |
