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…

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…

Effective thermal conductivity of helium II: from Landau to Gorter-Mellink regimes

Michele Sciacca, David Jou, Maria Stella Mongiovi'

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 cond…

Waves propagation in turbulent superfluid helium in presence of combined rotation and counterflow

Rosa Anna Peruzza, Michele Sciacca

A complete study of the propagation of waves (namely longitudinal density and temperature waves, longitudinal and transversal velocity waves and heat waves) in turbulent superfluid…

Non-equilibrium thermodynamics analysis of rotating counterflow superfluid turbulence

Michele Sciacca

In two previous papers two evolution equations for the vortex line density , proposed by Vinen, were generalized to rotating superfluid turbulence and compared with each other.…

A mathematical model of counterflow superfluid turbulence describing heat waves and vortex-density waves

Michele Sciacca, Maria Stella Mongiovi', David Jou

The interaction between vortex density waves and high-frequency second sound in counterflow superfluid turbulence is examined, incorporating diffusive and elastic contributions of…
