Spherically symmetric counterflow turbulence in open geometry
Tomáš Dunca, Filip Novotný, Marek Talíř +4
We report preliminary results on spherical thermal counterflow generated by a small central heater in an open geometry, an open bath of superfluid He~II, as closed-cell experiments…

Turbulent dissipative coupling in nanoscale multimode superfluid acoustics
Filip Novotný, Marek Talíř, Emil Varga
Superfluid helium, the inviscid low-temperature phase of liquid \4He, enables investigation of flows with reduced dimensionality since, due to the vanishing viscosity, sub-micron f…

Dynamics of quantum turbulence in axially rotating thermal counterflow
Ritesh Dwivedi, Tomáš Dunca, Filip Novotný +6
Generation, statistically steady state, and temporal decay of axially rotating thermal counterflow of superfluid He (He~II) in a square channel is probed using the second sound…
