Abstract
An expression for the spatial decay of an energy functional of solutions of the Navier-Stokes equations is given. The decay is exponential in nature with a decay constant which depends only on the geometry of the flow region.
Résumé
Nous exprimons la diminution par rapport à la distance d'une fonction d'énergie de certaines solutions des équations de Navier-Stokes. L'expression est du type exponentiel décroissant dont le coefficient ne dépend que de la forme de la région d'écoulement.
