Turbulent radial thermal counterflow in the framework of the HVBK model
Yuri A. Sergeev, Carlo F. Barenghi
We apply the coarse-grained Hall-Vinen-Bekarevich-Khalatnikov (HVBK) equations to model the statistically steady-state, turbulent, cylindrically symmetric radial counterflow genera…
Visualization of quantum turbulence in superfluid He-B: Combined numerical/experimental study of Andreev reflection
Viktor Tsepelin, Andrew W. Baggaley, Yuri A. Sergeev +5
We present a combined numerical and experimental study of Andreev scattering from quantum turbulence in superfluid He-B at ultralow temperatures. We simulate the evolution of m…
Helicity and topology of a small region of quantum vorticity
M. Mesgarnezhad, R. G. Cooper, A. W. Baggaley +1
We numerically study the evolution of a small turbulent region of quantised vorticity in superfluid helium, a regime which can be realised in the laboratory. We show that the turbu…
Large-scale normal fluid circulation in helium superflows
Luca Galantucci, Michele Sciacca, Carlo F. Barenghi
We perform fully-coupled numerical simulations of helium II pure superflows in a channel, with vortex- line density typical of experiments. Peculiar to our model is the computation…
A superfluid boundary layer
G. W. Stagg, N. G. Parker, C. F. Barenghi
We model the superfluid flow of liquid helium over the rough surface of a wire (used to experimentally generate turbulence) profiled by atomic force microscopy. Numerical simulatio…
Coupled normal fluid and superfluid profiles of turbulent helium II in channels
Luca Galantucci, Michele Sciacca, Carlo F. Barenghi
We perform fully coupled two--dimensional numerical simulations of plane channel helium II counterflows with vortex--line density typical of experiments. The main features of our a…
