| Guidelines |
| The investigation of superfluid helium flows is an active and challenging research field. Progress in our phenomenological understanding of the underlying physics has been achieved in recent years by employing flow visualization techniques that allow following the motion of relatively small particles suspended in the fluid. The work focuses on the experimental analysis by visualization of the particle dynamics in the proximity of solid boundaries, as the corresponding fluid behaviour is still largely unknown. Its aim is therefore to give a significant contribution to the promising line of scientific enquiry dedicated to the study of wall-bounded quantum flows. |
