Abstract:
We show that in the self-consistent equations for equal-time correlation
functions of velocity fluctuations obtained in the model of developed
turbulence based on the maximal randomness principle, infrared divergences
are absent from all orders of the perturbation theory. We analyze the additional ultraviolet (UV) divergences that appear in the two-loop approximation of the self-consistent equations. We show that in the system with conserved parity, these divergences can be eliminated using the existing ambiguity in the solution. In the case of parity violation in the system, the UV divergences have a logarithmic form, which can indicate a deviation from the Kolmogorov scaling.
Keywords:
self-consistency equation, Kolmogorov power law, helicity, parity violation, infrared divergence, ultraviolet divergence.
