Stability of power-law weak-turbulence distributions in superfluid helium
Belavin V. A. , Kolmakov G. V.
The stability of power-law spectra of acoustic turbulence in superfluid helium is analyzed. Such spectra are shown to be unstable with respect to isotropic perturbations and also with respect to perturbations which have the angular distribution of the first spherical harmonic. Corrections to the distributions for the onset of this instability are derived. © 1995 American Institute of Physics.
