The paper presents an extended review of our knowledge and understanding of turbulence
in a superfluid (4 He and 3 He-B), a system in which turbulent flow can be greatly influenced …

The detailed nature of fluid flow over a cylinder is one of the fundamental topics in classical
fluid dynamics as it demonstrates flow separation and vortex shedding. In superfluid helium …

Recent experiments have shown that it is possible to implement particle image velocimetry
(PIV) in liquid helium. However, to interpret the PIV data in the superfluid phase, it is …

Obtaining turbulence statistics in particle-laden flows using optical whole-field
measurements is complicated due to the inevitable data loss. The effects of this data loss are …
