Jet Velocity Dissipation And Modelling With Aeration, Stephen J. Schlenker
Jet Velocity Dissipation And Modelling With Aeration, Stephen J. Schlenker
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The effects of natural aeration and fall height upon velocity dissipation and modelling were studied. Underwater velocities and void ratios (proportion of air volume to total volume) were measured along the jet centerline at various depths in the receiving pool under 1- and 2-inch diameter vertical circular free-falling jets. Maximum air bubble penetration depths were also measured. In the tests, the nozzle velocities were designed so that the two differently sized models would have equivalent Froude numbers for direct comparison of respective underwater parameters. Air entrainment-the natural development of air bubbles within a pool receiving a free-falling jet-causes voids to …
