Energy spectra of developed turbulence in helium superfluids

Abstract

We suggest a 'minimal model' for the 3D turbulent energy spectra in superfluids, based on their two-fluid description. We start from the Navier-Stokes equation for the normal fluid and from the coarse-grained hydrodynamic equation for the superfluid component and introduce a mutual friction coupling term.
