The energy dissipation of quasiclassical homogeneous turbulence in superfluid $^4$He (He II) is controlled by an effective kinematic viscosity $\nu'$, which relates the energy decay rate $dE/dt$ to the density of quantized vortex lines $L$ as $dE/dt=

Thermal counterflow of normal and superfluid components in superfluid helium leads to a form of turbulence confined to the superfluid component. Contrary to usual assumptions, these vortex filaments are shown to induce a strongly nonuniform flow in t

We report preliminary results of a systematic study of the flow of normal fluid component in steady-state quantum turbulence in thermal counterflow of superfluid \(^{4}\hbox {He}\) using a high-precision flow visualisation technique based on the trac

We summarize recent experiments on thermal counterflow turbulence in superfluid 4He, emphasizing the observation of turbulence in the normal fluid and its effect on the decay process when the heat flux is turned off. We argue that what is observed as

There are two commonly discussed forms of quantum turbulence in superfluid $^4$He above 1K: in one there is a random tangle of quantizes vortex lines, existing in the presence of a non-turbulent normal fluid; in the second there is a coupled turbulen

This chapter aims to show that there is a remarkably close similarity between superfluid helium and a superconductor in very many essential properties. An important is that for a complete understanding of superfluidity we ought really to study both s

Recent preliminary experiments [A. Marakov et al., Phys. Rev. B 91, 094503 (2015).] using triplet-state ${\mathrm{He}}_{2}$ excimer molecules as tracers of the motion of the normal fluid have shown that, in thermal counterflow turbulence in superflui
