[Laminar forced convection wake above a heated plate placed in a channel]
In this Note, a numerical investigation of laminar convection wake above a heated plate placed in a channel is carried out. An analytical study based on a three region structure is proposed in the immediate neighbourhood of the trailing edge. Velocity and temperature at the centerline channel as well as the pressure gradient are presented in asymptotic expressions. Comparison of these results with numerical solutions enhances the analytical study.
Dans ce travail, la convection laminaire forcée dans le sillage d'une plaque chaude placée au milieu d'un canal est traitée numériquement. En aval immédiat du bord de fuite, on propose une étude analytique basée sur une structure de trois couches. La vitesse et la température sur l'axe central du canal ainsi que le gradient de pression sont présentés sous formes asymptotiques. La comparaison des résultats numérique et asymptotique met en valeur l'étude analytique, et montre qu'elle décrit l'essentiel de l'évolution du sillage.
