Universal dissipation scaling for non-equilibrium turbulence
Abstract
It is experimentally shown that the non-classical high Reynolds number energy dissipation behaviour, Cε ε L/u3 = f(ReM)/ReL, observed during the decay of fractal square grid-generated turbulence is also manifested in decaying turbulence originating from various regular grids. For sufficiently high values of the global Reynolds numbers ReM, f(ReM) ReM.
