Ultrasound-controlled Taylor-mode breakup of liquid jets

We present a resonant liquid capillary wave theory which extends Taylor´s dispersion relation to include the effect of surface inclination caused by air flow. Also reported are new experimental results on effects of surface tension and air velocity on drop-size distributions in comparison to the theoretical predictions. Good agreements between the theoretical predictions and the experimental results led to the conclusion that Taylor-mode breakup plays a very important role in two-fluid atomization. Further, this ultrasound-controlled breakup provides a means for controlling the drop size and size distribution in two-fluid atomization which has a variety of applications in fuel combustion, spray drying, and spray coating
