Interaction of parallel turbulent plane jets

Abstract

Research was done on the interaction of two plane parallel turbulent jets issuing into a still surrounding. Because of the entrainment of surrounding air, the two jets attracted each other, merged together, and eventually combined to resemble a single jet. Thus, the flowfield can be defined by three regions: 1)the converging region; 2)the merging region; and 3)the combined region. Te mean velocities, mean flow directions, turbulent intensities, and Reynolds shear stress of these three regions were measured by using a split-film probe on a constant temperature anemometer
