Abstract

This study aims to obtain basic knowledge on the atomization by unlike-jet impingement which may be of use for simultaneous atomization and effective mixing of two liquids. A radial compound liquid-sheet jet was formed by normal impingement of two liquid-jets of immiscible liquids – water-solution of propylene-glycol and silicone oil #10. The breakup behavior of liquid-sheet was observed by the two-color flash photography. The breakup radius of liquid-sheet and the number of perforations on liquid-sheet were evaluated from the images. The mean diameter of produced droplets was measured by the laser-diffraction method. Sampling the droplets by the oil-sensitive paper, the configuration of individual droplets was also investigated. The results were compared with those of conventional liquid-sheet formed by alike-jets impingement, and the breakup process of the compound liquid-sheet was discussed.
