Abstract
We describe experiments in the Benard-von Karman hydrodynamic instabil ity of the vortex shedding behind an obstacle. We obtain the scaling l aws for the evolution of the global mode describing the envelope of th e peak to peak amplitude velocity oscillation of the flow velocity and we show the existence of a universal curve for the renormalized ampli tude of the streamwise evolution of this amplitude.
