摘要: We present the first observation of grid-generated two-dimensional turbulence in a thin fluid film. The evolution vortex sizes, processes merging and general aspect velocity field correspond qualitatively to theoretical predictions recent numerical simulations On observe la derriere un peigne tire dans film liquide mince. L'evolution de taille des tourbillons, les processus fusion tourbillons et l'aspect du champ vitesse correspondent qualitativement aux prevision theoriques recentes concernant bidimensionnelle
