We obtain upper bounds on energy dissipation in Couette-Ekman flow by means of the Doering-Constantin method of the optimum theory of turbulence. We use one-component and two-component background velocity fields and investigate the application areas for the background fields with respect to the Reyn

We extend the Doering-Constantin approach to upper bounds on energy dissipation in turbulent flows by introducing a balance parameter into the variational principle. This parameter governs the relative weight of different contributions to the dissipation rate. Its optimization leads to improved boun
