Abstract

Experiments have found that freely relaxing turbulence in inviscid, incompressible two-dimensional Euler flows can self-organize into ordered structures-vortex crystals-in which a number N_c˜2-20 of strong vortices form stable, rigidly rotating patterns in a low vorticity background. In this paper we show that N_c can be roughly predicted from properties of the flows in the early stage of the turbulent relaxation.
