Abstract

The analysis of quantum signature of superfluid turbulence was presented. Prediction of the pressure spectrum of superfluid turbulence dependence on the wave number, which represented a macroscopic quantum signature not be found in the classical Kolmogorov theory of turbulence was done using numeical simulation backed up by physical arguements. The similarities between classical turbulence and helium II turbulence were investigated by the analysis of the pressure field spectrum.
