  • Decay of the vortex tangle at zero temperature and quasiclassical turbulence 
    Nemirovskii, S.K. (Физика низких температур, 2013)
    We review and analyze a series of works, both experimental and numerical and theoretical, dealing with the decay of quantum turbulence at zero temperature. Free decay of the vortex tangle is a key argument in favor of the ...
  • Energy spectrum of the quantum vortices configurations 
    Nemirovskii, S.K. (Физика низких температур, 2015)
    The energy spectra of the 3D velocity field, induced by various vortex filaments configurations are reviewed. The especial attention is paid to configurations generating the Kolmogorov type energy spectrum E(k) ∝ k⁻⁵/³. ...
  • Hydrodynamic impulse and energy of vortex tangle in superfluid turbulent He-II 
    Nemirovskii, S.K.; Lushnikov, V.A. (Физика низких температур, 1998)
    The average hydrodynamic impulse (or Lamb impulse) Jv in the counterflowing superfluid, turbulent He-II and the kinetic energy E, which is associated with the chaotic vortex filaments, are calculated. These quantities ...
  • Method of trial distribution function for quantum turbulence 
    Nemirovskii, S.K. (Физика низких температур, 2012)
    Studying quantum turbulence the necessity of calculation the various characteristics of the vortex tangle (VT) appears. Some of "crude" quantities can be expressed directly via the total length of vortex lines (per unit ...
  • Numerical study of the diffusive-like decay of the vortex tangle without mutual friction 
    Kondaurova, L.P.; Nemirovskii, S.K. (Физика низких температур, 2011)
    The numerical simulation of the diffusive-like decay of the vortex tangle without mutual friction was performed. The simulation was made with the use of the localized induction approximation. The early developed by authors ...
  • Probing of quantum turbulence with the emitting vortex loops 
    Nemirovskii, S.K. (Физика низких температур, 2014)
    The statistics of vortex loops emitted from the domain with quantum turbulence is studied. The investigation is performed on the supposition that the vortex loops have the Brownian or random walking structure with the ...
  • Simulation of stochastic vortex tangle 
    Kondaurova, L.P.; Nemirovskii, S.K.; Nedoboiko, M.V. (Физика низких температур, 2003)
    We present the results of simulation of the chaotic dynamics of quantized vortices in the bulk of superfluid He II. Evolution of vortex lines is calculated on the base of the Biot-Savart law. The dissipative effects appeared ...
  • Torsional oscillation of the vortex tangle. Possible applications to oscillations of solid ⁴He 
    Nemirovskii, S.K. (Физика низких температур, 2011)
    Torsional oscillation of the vessels with quantum fluids is one of oldest and most popular methods for the study of quantized vortices. The recent and very bright example is the discovery of the supersolidity of the solid ...
