Available in PDF, EPUB and Kindle. Book excerpt: The spray formed by two impinging liquid jets was investigated over a jet velocity range of 5 to 100 feet per second to determine the characteristics of this method of atomization. At low velocities the spray pattern was a smooth sheet completely surrounded by a liquid rim. As jet velocity increased, the rim separated at the downstream end. As jet velocity increased, the rim separated at the downstream end. In this flow region an alternate spray pattern wit ha rippled sheet and periodic drops can occur. At higher jet velocities a fully developed spray was produced which was characterized by waves of drops. The wave pattern was more distinct with high-viscosity fluids. The frequency of the waves in the fully developed spray increased with increased injection velocity and decreasing impingement angle. Jet diameter and length before impingement had a negligible effect on the wave frequency. Characteristics of single jets were the same as determined by other investigators.
