Nv. Antonov et Av. Runov, RENORMALIZATION-GROUP IN THE THEORY OF 2-DIMENSIONAL TURBULENCE - INSTABILITY OF THE FIXED-POINT WITH RESPECT TO WEAK ANISOTROPY, Theoretical and mathematical physics, 112(3), 1997, pp. 1131-1139
A statistical model of fully developed turbulence in two-dimensional s
pace is considered by means of the renormalization group method in the
weak anisotropy approximation. It is shown that the corresponding fix
ed point of the renormalization group equations is not infrared stable
. Hence, the weak anisotropy approximation is not valid for describing
two-dimensional turbulence.
