This review paper puts together some results concerning non equilibrium thermodynamics
and heat transport properties of superfluid He II. A one-fluid extended model of superfluid …

At the very heart of turbulent fluid flows are many interacting vortices that produce a chaotic
and seemingly unpredictable velocity field. Gaining new insight into the complex motion of …

We report a comprehensive study of turbulent superfluid 4 He flow through a channel of
square cross section. We study for the first time two distinct flow configurations with the same …

Superfluid helium is an intimate mixture of a viscous normal fluid, with continuous vorticity,
and an inviscid superfluid, where vorticity is constrained to thin, stable topological defects …

We perform numerical simulations of finite temperature quantum turbulence produced
through thermal counterflow in superfluid^ 4 4 He, using the vortex filament model. We …

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 …

The problem of quantum turbulence in a channel with an inhomogeneous counterflow of
superfluid turbulent helium is studied. The counterflow velocity V nsx (y) along the channel is …

The size-dependent and flux-dependent effective thermal conductivity of narrow channels
filled with He II is analyzed. The classical Landau evaluation of the effective thermal …

In this paper, the velocity profile of the normal component in the stationary flow of turbulent
superfluid helium inside a cylindrical channel is determined, making use of a one-fluid …

The hydrodynamic problems of superfluid fluid containing chaotic tangles of quantized
vortex filaments are discussed. The construction of such hydrodynamics crucially depends …
