Jl. Ottinger et D. Carati, RELATION BETWEEN INFORMATION-TRANSFER AND STRUCTURE-FUNCTION IN SHELLMODELS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 53(1), 1996, pp. 601-610
Shell models with conservation properties corresponding to two- and th
ree-dimensional turbulence are presented together with other test mode
ls. Symmetry breaking in the information transfer between large and sm
all scales is shown to be responsible for the convexity or the concavi
ty of the scaling exponents of the structure function associated with
intermittency corrections. The same effect is discussed in other model
s of intermittency.
