Pattern Formation in Fluid Mechanics

Complex behaviour of large scale features of fully turbulent flows.

Author: Louis Marié (Laboratoire de Physique des Océans, Brest, France)


It is usually believed that the very large level of noise arising from small-scale structures of turbulent flows precludes their large scale features from displaying complex behaviour.

At variance with this widely accepted view, we will present recent experimental results obtained in two different flow configurations which show that non-trivial large-scale behaviour can persist even when considerable small-scale activity is present.
