“…[1][2][3][4][5][6][7] Martinuzzi and Tropea [4] investigated flow characteristics over surfacemounted ribs with 11 different aspect ratios (AR, defined as the ratio of rib width to rib height) ranging from 1 to 24. The effect of the ribs on the flow pattern was classified to be either two-dimensional (2D) or 3D depending on AR.…”

“…We have chosen to use the ow across a step since recirculation of a ow is a very natural situation. Applications of the study herein include 'wind engineering and many uid devices, such as weirs, gas turbines, turbo machines and combustion ducts' [18]. More motivation for the choice of this test problem is given at the beginning of Section 3.…”

“…Nous traitons davantage de cet élément dans la section suivante où nous introduisons la notion de perméabilité qui est la propriété d'un milieu poreux à permettre un écoulement fluide à travers un réseau de canaux interconnectés les uns avec les autres [14] Derrière l'obstacle, on retrouve une région abritée caractérisée par la présence d'un champ de pression horizontal qui s'étend le long de la paroi solide sur une distance correspondant de 10 à 15 fois la hauteur de l'obstacle [1]. La distribution de la pression à la paroi derrière l'obstacle (p w ) peut être exprimée en fonction d'un coefficient de pression (C p ) caractéristique de la géométrie de l'obstacle, de la masse volumique de l'eau de mer (pj , de la vitesse du courant (U(t)) et de la pression à l'équilibre (p eq ) retrouvée au loin de l'obstacle tel que [24]:…”
