[Sur l'alternative tri-dimensionnelle à la solution de couche limite de Blasius]
Des investigations théoriques ont montré qu'une alternative tridimensionnelle à la solution de Blasius existe pour l'écoulement en couche limite laminaire sur une plaque plane semi-infinie à incidence nulle. Dans cette Note, on montre numériquement qu'il existe une classe des solutions tridimensionnelles confinée au cas correspondant à une plaque plane presque à incidence nulle.
Theoretical investigations have shown that there is a three-dimensional alternative to the Blasius solution for laminar boundary layer flow past a semi-infinite flat plate at zero incident. In this Note we show numerically that there exists a class of three-dimensional solutions confined to almost zero incident conditions.
