MEASUREMENTS OF TURBULENT INCLINED PLANE DUAL JETS

Measurements of mean velocities, flow direction, velocity fluctuations and Reynolds shear stress were made with a split film probe of hot wi re anemometer to investigate the interactions created by two air jets issuing from two identical plane inclined nozzles. The reverse flow wa s detected by using the split film probe and observed by flow visualiz ation. Experimental results with an inclined angle of 9-degrees are pr esented in the paper. Some experimental results with an inclined angle of 27-degrees are presented to investigate the effect of inclination on the flow field. Mean velocities approach self-preservation in both the converging region and the combining region. Velocity fluctuations and Reynolds shear stress approach self-preservation in the combining region only. The spreads.of jet and the square of the decay of maximum mean velocity increase linearly as the distance from the nozzle exit increases.
