Impact Region of Nonbuoyant Orthogonal Discharge

Publication: Journal of Hydraulic Engineering
Volume 147, Issue 12

Abstract

The results of experimental studies into the behavior of nonbuoyant discharges impacting a solid boundary are presented. The discharges were released perpendicular to the boundary at nondimensional heights (H/d) ranging from to 36 to 173, where H/d is the ratio of the jet discharge height above the boundary to the jet diameter. Although the primary focus was on concentration field measurements using a laser-induced fluorescence system, additional velocity field data are presented from a recent study that used a similar discharge configuration and a particle tracking velocimetry system. Integral models provided a relatively simplistic framework for quantifying and interpreting the flow behavior in the vicinity of the boundary. The new data sets enabled defining the scale of the impact region based on the ability of integral techniques to model the flow entering and leaving this region. These data sets also offered insights into the flow behavior in the impact region and provided the basis for determining the influence of the impact region on the flow behavior.
