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…
Vortex density waves and high-frequency second sound in superfluid turbulence hydrodynamics
David Jou, Maria Stella Mongiovi'and Michele Sciacca
In this paper we show that a recent hydrodynamical model of superfluid turbulence describes vortex density waves and their effects on the speed of high-frequency second sound. In t…
The saturation of decaying counterflow turbulence in helium II
Michele Sciacca, Yuri A. Sergeev, Carlo F. Barenghi +1
We are concerned with the problem of the decay of a tangle of quantized vortices in He II generated by a heat current. Direct application of Vinen's equation yields the temporal sc…
Vortex length, vortex energy and fractal dimension of superfluid turbulence at very low temperature
David Jou, Maria Stella Mongiovi', Michele Sciacca +1
By assuming a self-similar structure for Kelvin waves along vortex loops with successive smaller scale features, we model the fractal dimension of a superfluid vortex tangle in the…
