Experimental characterization of the initial zone of an annular jet with a very large diameter ratio.

Résumé

This article presents an experimental investigation of a large diameter ratio annular air jet by Particle Image Velocimetry (P.I.V.), Laser Doppler Anemometry (L.D.A.), hot wire anemometry and time-resolved tomography. Annular jets consist in a round nozzle with an obstacle placed in its center. These jets are thus defined by an external and an internal diameter corresponding to the round nozzle lips and the diameter of the obstacle respectively. The ratio between these two diameters defines the behavior of the flow across a characteristic diameter called diameter ratio. In most industrial applications these jets have large diameter ratios, superior to 0.7.
