Public ISBD Titre : Hydraulic model studies - Aeration of the submerged jet - Flow gates at seminoe dam Type de document : texte imprimé Auteurs : Frizell, K. W. Mention d'édition : U.S. Departement of the interior Editeur : U.S. Departement of the Interior Année de publication : 1990 ISBN/ISSN/EAN : CI-06871 Note générale : A study was performed to evaluate placement of an aeration vent on a submerged jet. Flow gate at seminoe dam. Size restrictions on the discharge tube downs tream from the gate suggested aeration as a means to project the downstream areas from cavitation damage. Four air vent location were tested. The vent on the top centerline of the discharge tube just downstream of the gate frame performed the best. Ratios of Qo/Qw greater than 10 percent were measured throught the entire range of gate openings. A minimum vent size of 16 inches in diameter is needed to keep air velocities through the vent below 200 p+/S.
