Abstract

Dye visualization techniques have been used to study the flow structures of a round jet in a cross-flow at a velocity ratio (R=Vjet/Uo) of four. The study has revealed some interesting flow features including a small separation region which occurs just below the upstream lip of the pipe exit and that the jet shear layer rolls up to produce distorted ring vortices which tilt and fold with streamwise distance. These and other flow features are analyzed with the aid of critical point theory.
