[Un modèle stationaire de Navier–Stokes pour fluide incompressible avec des solutions partiellement fortes]
Dans cette Note, nous démontrons l'existence de solutions partiellement fortes pour les équations de Navier–Stokes stationnaires descriptives de fluides visqueux barotropiques compressibles, dans un domaine borné de , avec des conditions aux limites d'imperméabilité généralisée , . Nous utilisons le libellé « solution partiellement forte » pour dire que les propriétés de régularité de la partie à divergence nulle du champ des vitesses et de la pression effective associée sont typiques d'une solution forte, tandis que les propriétés de régularité de la densité et de la partie complémentaire du champ des vitesses (gradient d'un potentiel) sont typiques d'une solution faible.
In this Note, we prove the existence of a partially strong solution to the steady Navier–Stokes equations for viscous barotropic compressible fluids, in a bounded simply connected domain of with the prescribed generalized impermeability conditions , on the boundary. We call the solution “partially strong” because only the divergence-free part of the velocity field and the associated effective pressure have regularity typical for strong solution, while the density and the gradient part of the velocity have regularity typical for weak solution.
