Kurzfassung
Experiments were conducted in a low-speed wind tunnel to understand the influence of nozzle geometry on the flow characteristics of incompressible air jets injected normal to a freestream. Jets issuing from circular and noncircular nozzles, with exit Reynolds numbers in the range 4500-9200 and velocity ratios from 3.8 to 7.7 are investigated. Measurements, in the zone of established flow, were carried out by laser light sheet flow visualization coupled with image processing, and laser Doppler anemometer techniques. Results show that, with increasing aspect ratio of the nozzles, the jet penetration increases ans carries stronger bound vortex pairs compared with the circular case. The deflected circular and square jets exhibit similar flow characteristics.
