It is experimentally shown that the nonclassical high Reynolds number energy dissipation behavior, C-g epsilon L/u(3) = f(Re-M)/Re-L, observed during the decay of fractal square grid-generated turbulence (where Re-M is a global inlet Reynolds number and Re-L is a local turbulence Reynolds number) is also manifested in decaying turbulence originating from various regular grids. For sufficiently high values of the global Reynolds numbers Re-M, f(Re-M) similar to Re-M.
