Mi, J. and Deo, R. C. and Nathan, G. J. (2005) Characterization of turbulent jets from high-aspect-ratio rectangular nozzles. Physics of Fluids, 17 (6). pp. 1-4. ISSN 1070-6631
Abstract
Turbulent free jets issuing from rectangular slots with various high aspect ratios s15–120d are characterized. The centerline mean and rms velocities are measured using hot-wire anemometry over a downstream distance of up to 160 slot heights at a slot-height-based Reynolds number of
10 000. Experimental results suggest that a rectangular jet with sufficiently high aspect ratios (>= 15) may be distinguished between three flow zones: an initial quasi-plane-jet zone, a transition zone, and a final quasi-axisymmetric-jet zone. In the quasi-plane-jet zone, the turbulent velocity field is statistically similar, but not identical, to those of a plane jet.
