Energy spectra of developed superfluid turbulence

Chaotic Dynamics 2009-11-10 v3 Soft Condensed Matter

Abstract

The spectrum of turbulence in superfluid liquid is modified by the nonlinear energy dissipation caused by the mutual friction between quantized vortices and the normal component of the liquid. In some region of two Reynolds parameters characterizing the flow of a superfluid, we found the new state of the fully developed turbulence. This state displays both the Kolmogorov-Obukhov 5/3-scaling law Ekk5/3E_k \propto k^{-5/3} and the new "3-scaling law" Ekk3E_k \propto k^{-3}, each in a well separated range of kk.
