Mechanically versus thermally generated quantum turbulence of 4He superflow
An experiment on thermally driven 4He superflow (Chagovets and Skrbek in Phys. Rev. Lett. 100:215302, 2008; J. Low Temp. Phys. 153:162, 2008) yielded very different steady state turbulence properties from a nominally identical recent that di...

Coexistence and interplay of quantum and classical turbulence in superfluid He-4: Decay, velocity decoupling, and counterflow energy spectra
We report complementary experimental, numerical, and theoretical study of turbulent coflow, counterflow, and pure superflow of superfluid He-4 in a channel of steady-state quantum turbulence in the counterflow and pure superflow, ba...

Vortex flow in rotating superfluid He-3-B
For investigating vortex formation in rotating superfluid He-3-B at high velocities of vortex-free superflow, the usual geometry is a cylindrical sample, which is connected via an orifice and a liquid He-3 column to the heat exchang...

Steady and Decaying Quantum Turbulence Generated in He II Flow by Counterflow and Pure Superflow
Turbulence state in superfluid He II was generated by counterflow or pure superflow in channels of circular and square crossection. Vortex line density was detected by second sound attenuation measurements. The new data on the steady state a...
