An Exact Renormalization Group analysis of 3-d Well Developed turbulence
We take advantage of peculiar properties of three dimensional incompressible
turbulence to introduce a nonstandard Exact Renormalization Group method. A
Galilean invariance preserving regularizing procedure is utilized and a field
truncation is adopted to test the method. Results are encouraging: the energy
spectrum E(k) in the inertial range scales with exponent -1.666+/- 0.001 and
the Kolmogorov constant C_K, computed for several (realistic) shapes of the
stirring force correlator, agrees with experimental data.Comment: 12 pg, 2figures, LaTex, To be published on Physics Letters
