| 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 5/3-scaling law Ek ∝ k?5/3 and a new “3-scaling law” Ek ∝ k?3, each in a well-separated range of k. |
