Universal dissipation scaling for non-equilibrium turbulence

Abstract

It is experimentally shown that the non-classical high Reynolds number energy dissipation behaviour, $C_{\epsilon }\equiv \epsilon L/u^3=f(R{e}_M)/R{e}_L$, 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 $R{e}_M$, $f(R{e}_M)\sim R{e}_M$.
