Energy dissipation bounds for hear flows for a model in large eddy simulation

This report gives an upper bound for the time average of the energy dissipation rate, including energy dissipation due to viscous dissipation and turbulent diffusion in a model for the motion of large eddies in a turbulent flow. The bound is only a function of the reference velocity U, the domain diameter L, the eddy size δ, and surprisingly, the Reynolds number.
