“…In virtue of measuring the mass distribution and the atomizing Sauter Mean Diameter, a non-zero component of the moment in the direction of jet propagation was certified leading the formed liquid sheet to deflection when two misaligned jets impinged at one point. S.Bimal et al reported the allowable maximum misalignment of the jets and concluded that if the jet skewness exceeds some certain value, it turns to act as a controlling parameter to the atomization [20]. Despite the existing results, systematic investigation of the misaligned impinging effects on liquid sheet and atomization characteristics still merits efforts.…”

Atomization characteristics by impingement of circular arranged triple-jets is experimentally investigated in the present study with emphasis on the off-center impinging effects. Corresponding experimental apparatus was established to spatially and temporally capture the atomization process by employing a high-speed camera and Phase Doppler Particle Analyzer (PDPA). Jet impinging parameter, B, is defined to quantitatively describe the offcenter effect, and the desired value of B is guaranteed by the intelligent 3D-printing manufacturing technology. From the experimental results, the structure of liquid sheet and ligament formed by head-on and off-center impingement were both observed. It is found that firstly, there exists two types of the structure of the liquid sheet, i.e., closed rim and open rim, in the interested range of impinging conditions. Transition between the two regime is substantially affected by the combination of impinging We and B. Specifically, smaller B would be needed to achieve the open rim at larger impinging We. The results show that the larger value of B leads to smaller SMD of droplets Keywords atomization, jet impingement, spray characteristics, SMD, off-center effect.
