The investigation of superfluid helium flows is an active and challenging research field. Flow visualization techniques, which allow following the motion of relatively small particles suspended in the fluid, have in recent years given a significant contribution to our understanding of the underlying physics. New visualization experiments inside a purpose-made long channel, at various distances from the flow source, are currently being prepared, especially to address the still open question regarding the behaviour of superfluid helium flows in the proximity of solid boundaries. The work aim is to successfully implement adequate flow sources (such as heaters and electric motors) and sensors (for example, thermometers) in the current cryogenic visualization setup.
