Download or read book Fluctuations in a Spray Formed by Two Impinging Jets written by Marcus F. Heidmann and published by . This book was released on 1951 with total page 42 pages. 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.
