Relative scaling exponents of n-th - order velocity and temperature structure functions

Scaling exponents of the moments of the instantaneous velocity vector fluctuation increment, δq, and its components (δu, δv and δw) are compared with those of the temperature fluctuation increment, δθ, in the self-preserving region of a cylinder wake. Across the wake, δq scaling exponents compare more favorably to those of δθ than do δu with δθ mainly because δq is interdependent on δv and δw. The agreement between scaling exponents of δv or δw with those of δθ do not seem to depend on either the local mean shear or Rλ, although the individual magnitudes of these exponents increase with Rλ and decrease with the local mean shear.
