Temporal decay of vortex line density in rotating thermal counterflow of He II
Filip Novotný, Marek Talíř, Emil Varga +1
Horizontally () and axially () rotating counterflow of superfluid He (He~II) generated thermally i…
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…
Decay of two-dimensional superfluid turbulence over pinning surface
Filip Novotný, Marek Talíř, Emil Varga
We report on the free decay of quasi-two-dimensional turbulence in superfluid He confined within nanofluidic channels. Using a pump-probe technique, we observe a complex decay…
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…
