Emulsion droplet sizes are compared with rates of turbulent energy dissipation in various types of practical equipment. These rates can be very high locally-up to 400 MW . kg-' in valve homogenizers. The role of adsorbed surface tilms is discussed, and it is deduced that drop break-up involves an i

We drive an upper bound of the time averaged energy dissipation rate for boundary driven flows directly from the Navier-Stokes equations in R n. The upper bound is independent of the kinematic viscosity in accordance with Kolomogorov's scaling result.

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
