Scaling laws of wave-cascading superfluid turbulence
Phenomenological model is constructed for superfluid turbulence for two distinct energy cascade scenarios, sound wave cascade and critically-balanced Kelvin wave cascade, using the method for magneto-fluid turbulence theory. Excitations along dispersion relations are used as the primary energy reser...

Summary: | Phenomenological model is constructed for superfluid turbulence for two distinct energy cascade scenarios, sound wave cascade and critically-balanced Kelvin wave cascade, using the method for magneto-fluid turbulence theory. Excitations along dispersion relations are used as the primary energy reservoir. The spectral indices in the inertial range are estimated as −3/2 for the long-wavelength sound wave cascade, −3 in the direction to the mean filaments for the Kelvin wave cascade, and −5/3 perpendicular to the filament direction. |
