The present study aims to investigate the influence of the impinging angle, impingement distance, and injection pressure on the characteristics of a mutual impinging spray that is formed by the direct impact between two solid-cone sprays. In the present study, the droplet sizes and velocities are measured by the phase Doppler particle anemometer system and the overall shape of spray is recorded by a photographic technique. The distribution of liquid volume fraction is also measured by the self-manufactured patternator. The results for the mutual impinging sprays are also compared with those for single nozzle-injected sprays. The Sauter mean diameters measured in the interspray impingement system become 35 and 45% smaller for impingement distances of 20 and 50 mm, respectively, compared to those of a single nozzle-injected spray. For different impinging angles, i.e., 60° and 90°, the decreasing rate in droplet velocity is found to be about 60 and 70%, respectively, of that measured in the single nozzle-injected spray. It is confirmed that mutual impinging sprays may be an alternative way to enhance atomization, provided that such optimized conditions are found in engineering applications.
