Atomization patterns and breakup characteristics of liquid sheets formed by two impinging jets

ligament, are studied. The circumferentially space drops were shed from the periphery of the sheet, as well as the ligaments were fragmented from the leading edge of the sheet and then broke into droplets following the Rayleigh mechanism. The periodic waves from the point of impingement were apparent on the surface of the sheet. The impact waves caused early breakdown of the sheet downstream of the impingement point, whereas waves amplied by aerodynamic stresses controlled the breakdown of the rest of the sheet and the ligaments. The impinging jets for non-Newtonian uid are also investigated, two dierent ow patterns are observed.
