Cette animation montre que l’écoulement réel sur la plaque plane (ici un écoulement d’eau additionnée de particules brillantes) est assez peu différent de l’écoulement potentiel (non visqueux, tel que vue dans une cellule d’Hele-Shaw), du moins sur la face amont de la plaque. Par contre, au dos de la plaque (à son aval), l’écoulement réel révèle la présence de tourbillons, ce qui est le cas de la plupart des écoulements de culot de corps même profilés s’ils arborent un culot (ou une troncature du profil).
