We address scaling in inhomogeneous and anisotropic turbulent flows by deco
mposing structure functions into their irreducible representation of the SO
(3) symmetry group which are designated by j, m indices. Employing simulati
ons of channel flows with Re-lambda approximate to 70 we demonstrate that d
ifferent components characterized by different j display different scaling
exponents, but for a given j these remain the same at different distances h
am the wall. The j = 0 exponent agrees extremely well with high Re measurem
ents of the scaling exponents, demonstrating the vitality of the SO(3) deco
mposition.
