Par exemple, en plus des nombres adimensionnels présentés pour les équations de Navier–Stokes , les écoulements compressibles font intervenir le nombre de Mach défini par M = V C

A rotor-stator model of a turbogenerator has been developed to solve rotational velocity transients: to this end, the angular position of a beam cross section is considered as

Three main different aspects are to be noted between the two studies: Lygren and Andersson [1] have considered an infinite system with fully turbulent flow in merged layers, while

Large scale dynamics in a turbulent compressible rotor/stator cavity flow at high Reynolds number... rotor/stator cavity flow at high

Suivant l’analyse faite par Schlichting [19] dans le cas d’un disque tournant de rayon infini, on d´etermine des lois analytiques simples permettant de pr´evoir le

Recent comparisons with velocity measurements [1] have shown that, for the rotational Reynolds number Re = Ωb 2 /ν = 95000 (Ω the rate of rotation of the rotating disk and ν

Close to the hub at r ∗ = 0.44, the mean flow is well described by the Stewartson model (35): the tangential velocity in the rotor boundary layer reduces from the rotor speed value
