B. Dubrulle et F. Graner, ANALOGY BETWEEN SCALE SYMMETRY AND RELATIVISTIC-MECHANICS - II - ELECTRIC ANALOG OF TURBULENCE, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 56(6), 1997, pp. 6435-6442
In turbulent structure functions, we separate a nonuniversal part, dep
ending on the most frequent events, and a universal part, i.e., reduce
d structure functions. We focus on the universal contribution using on
ly scale symmetry arguments and an analogy with electricity developed
in our companion paper. A conservation law leads to a general scaling
and a method of computation of the reduced structure functions. Around
the infinite-Reynolds-number limit, we propose a perturbation develop
ment which is both regular and compatible with scale symmetry. This li
near approximation accounts for a large variety of turbulent flows, fr
om jet to boundary layer turbulence.
