Rooster Tail Wave Hydraulics of Chutes
Publication: Journal of Hydraulic Engineering
Volume 137, Issue 9
Abstract
Supercritical flow below chute piers generates an aerated flow known as rooster tail. Their behavior varies along the spillway or chute for different Froude numbers. This paper aims to analyze the effect of various parameters including the Froude number, approach flow depth, chute pier width, and presence of a deflector ramp on the rooster tail geometry. Aerator systems, which generally include deflectors in chutes, are effective in the generation of rooster tails. The interaction between a deflector and supercritical flow of chutes causes a higher rooster tail. New equations define the rooster tail geometry in the presence of a deflector. The air concentration profile was measured and the effects of deflectors on the air entrainment were studied.
