Universal dissipation scaling for non-equilibrium turbulence

Fluid Dynamics 2013-05-30 v1

Abstract

It is experimentally shown that the non-classical high Reynolds number energy dissipation behaviour, CϵϵL/u3=f(ReM)/ReLC_{\epsilon} \equiv \epsilon L/u^3 = f(Re_M)/Re_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 ReMRe_M, f(ReM)ReMf(Re_M)\sim Re_M.
