Download or read book Spatial Characteristics of Water Spray Formed by Two Impinging Jets at Several Jet Velocities in Quiescent Air written by Hampton H. Foster and published by . This book was released on 1960 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spatial characteristics of a spray formed by two impinging water jets in quiescent air were studied over a range of nominal jet velocities of 30 to 74 feet per second. The total included angle between the 0.089-inch jets was 90 deg. The jet velocity, spray velocity, disappearance of the ligaments just before drop formation, mass distribution, and size and position of the largest drops were measured in a circumferential survey around the point of jet impingement. Photographic techniques were used in the evaluations. The distance from the point of jet impingement to ligament breakup into drops was about 4 inches on the spray axis and about 1.3 inches in the radial position +/-90 deg from the axis. The distance tended to increase slightly with increase in jet velocity. The spray velocity varied from about 99 to about 72 percent of the jet velocity for a change in circumferential position from the spray axis to the +/-80 deg positions. The percentages tended to increase slightly with an increase in jet velocity. Fifty percent of the mass was distributed about the spray axis in an included angle of slightly less than 40 deg. The effect of jet velocity was small. The largest observed drops (2260-micron or 0.090-in. diam.) were found on and about the spray axis. The size of the largest drops decreased for an increase in radial angular position, being about 1860 microns (0.074 in.) at the +/-90 deg positions. The largest drop sizes tended to decrease for an increase in jet velocity, although the velocity effect was small. A drop-size distribution analysis indicated a mass mean drop size equal to 54 percent of an extrapolated maximum drop size.

Available in PDF, EPUB and Kindle. Book excerpt: An investigation of two impinging jets of water showed that the liquid sheet formed on impingement disintegrates intermittently, forming groups of drops, which appear as waves propagating from the point of impingement. The frequency of wave occurrence was determined and the variation in frequency with jet velocity, impingement angle, jet diameter, and jet length was measured. The frequency varied between 1000 and 4000 cycles per second for the test conditions used. Photographs of spray pattern are presented.

This book was released on 1961 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sprays produced by two 0.089-inch-diameter jets at impingement angles of 10 to 90 degrees and jet velocities of 30 to 74 feet per second were studied. Drop-size distributions for sprays formed in 100-foot-per-second air are presented. Distributions were bimodal in character, and the effects of test conditions on the bimodal properties are presented. Photographs of the overall spray pattern produced in quiescent air are also shown.

Download or read book A Study of Sprays Formed by Two Impinging Jets written by Marcus F. Heidmann and published by . This book was released on 1957 with total page 32 pages. 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.
