Abstract

Experiments were conducted in a low-speed wind tunnel to understand the contrast between non-circular and circular turbulent jets in a cross-flow. The investigation involved flow conditions of incompressible momentum jets with exit Reynolds numbers in the range of 4500 to 9200. The study included the range of velocity ratios from 3.8 to 7.7 and is confined to the zone of established flow. The time-mean and statistical characteristics of the flowfield were measured by a 3-component LDA. The study revealed that the flow field downstream of rectangular deflected jet was more asymmetric than in a circular case and the tendency to acquire self-similarity of mean velocity profiles in relatively weak.
