IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Mixing behavior of 45 inclined dense jets in co-flowing currents
Author : MINGTAO JIANG(1), BAOXIN JIANG(2), ADRIAN WING-KEUNG LAW (2,3)
The mixing behavior of 45 inclined dense jets in co-flowing currents was examined experimentally by employing the advanced laser imaging technique of Planar Laser Induced Fluorescence (PLIF) at the jet centre plane. The experiment covered a wide range of jet densimetric Froude number (Fr) and jet to ambient velocity ratio (r). The results indicated that the mixing behavior is strongly dependent on the nominal Froude number (or ambient Froude number) NFr Ua /  gD .
For NFr<1.0, the mixing is jet dominated, and the trajectory is mainly affected by the initial jet momentum while the dimensionless centerline peak height Zm/FrD is almost independent of the nominal Froude number. For NFr≥1.0, the mixing behavior is strongly affected by the co-flowing currents, and the dimensionless centerline peak height Zm/FrD is a
function of NFr.
