Description
Français : Français : L'écoulement théorique d'un jet pariétal de largeur h le long d'une paroi circulaire de rayon r est calculé en appliquant les formules (27) et (29) de L.C. Woods: Compressible subsonic flow in two-dimensional channels with mixed boundary conditions, in: Quart. Journ.Mech.and Applied Math., Vol VII, Pt.3 (1954). L'angle de déviation doit être fixé: on prend celui qui a été mesuré expérimentalement en 1956 par l'auteur, et on le compare ici à l'angle de décollement trouvé par un calcul de couche limite ( Kadosch M.: Commande par fluide. Calcul de la déviation d'un jet par une paroi courbe in: Société Hydrotechnique de France, IXèmé Journées de l'Hydraulique, Paris, 1966). La répartition de pression théorique est comparée à la répartition expérimentale: Kadosch M.: Déviation d'un jet par adhérence à une paroi convexe, in: Journal de Physique et le Radium, Paris, Avril 1958, p. 9A

English: Inviscid flow of a wall jet of width h along a circular wall of radius r is calculated using formulae (27) and (29) from L.C. Woods: Compressible subsonic flow in two-dimensional channels with mixed boundary conditions, in: Quart. Journ.Mech.and Applied Math., Vol VII, Pt.3 (1954). The deviation angle must be given for the calculation: the angle found in experiments made by the author M. Kadosch in 1956 was chosen, and is here compared with the separation angle found in a calculation of the separation of the boundary layer due to the calculated pressure gradient along the wall (Kadosch M.: The curved wall effect in: 2nd Cranfield Fluidics Conference, Cambridge, 1967-01-03). Also this theoretical pressure is compared with the experimental pressure along the wall found by the author Kadosch M.: Déviation d'un jet par adhérence à une paroi convexe, in: Journal de Physique et le Radium, Paris, Avril 1958, p. 9A Date 7 mai 2015, 18:57:44 Source Travail personnel, in: Illusions créatrices, CreateSpace/Kindle 2015, pp.106 et 100
