✦ Synopsis

Measurements of mean velocities, flow direction, velocity fluctuations and Reynolds shear stress were made with a split film probe of hot wire anemometer to investigate the interactions created by two air jets issuing from two identical plane inclined nozzles. The reverse flow was detected by using the split film probe and observed by flow visualization. Experimental results with an inclined angle of 9 ~ are presented in the paper. Some experimental results with an inclined angle of 27 ~ 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.
