New experimental set-up to analyse cryogenic flows by visualisation

The first laboratory in Europe for visualisation of liquid helium flows is currently being established at the Charles University in Prague. The use of such a valuable experimental approach for the analysis of cryogenic flows of normal and superfluid 4He is introduced and its specific features discussed. More importantly, it is shown that the newly implemented flow visualisation equipment is potentially capable of obtaining novel results, i.e. further understanding of the involved physics.
