摘要：

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 delta, and surprisingly, the Reynolds number. (C) 2002 Elsevier Science Ltd. All rights reserved.
