Energy spectra of developed superfluid turbulence
PACS: 43.37.+q, 47.32.Cc, 67.40.Vs, 67.57.Fg
Abstract
Turbulence spectra in superfluids are modified by the nonlinear energy dissipation caused by the mutual friction between quantized vortices and the normal component of the liquid. We have found a new state of fully developed turbulence which occurs in some range of two Reynolds parameters characterizing the superfluid flow. This state displays both the Kolmogorov-Obukhov \frac53-scaling law E_k \propto k^{-5/3} and a new "3-scaling law" E_k \propto k^{-3}, each in a well-separated range of k.
