M. Hnatich et al., Stability of scaling regimes in d >= 2 developed turbulence with weak anisotropy - art. no. 016312, PHYS REV E, 6401(1), 2001, pp. 6312
Fully developed turbulence with weak anisotropy is investigated by means of
the renormalization group approach and double expansion regularization for
dimensions d greater than or equal to 2. Some modification of the standard
minimal subtraction scheme has been used to analyze the stability of the K
olmogorov scaling regime which is governed by the renormalization group fix
ed point. This fixed point is unstable at d = 2; thus the infinitesimally w
eak anisotropy destroys the above scaling regime in two-dimensional space.
The restoration of the stability of this fixed point, under a transition fr
om d = 2 to 3, is demonstrated at a borderline dimension 2 < d(c) < 3. The
results are in qualitative agreement with results recently obtained in the
framework of a typical analytical regularization scheme.
