Ultrasonic atomizers are capable of producing aerosols with narrow droplet size distribution. Formation of plume and splashes in the liquid are major concerns with the ultrasonic atomizers. In this study, we aimed at developing a two-stage atomization technique to resolve those issues associated with common ultrasonic atomizers. This new spray solution is designed with a cost-effective swirl-assisted sprinkling stage followed by a sonication stage using an ultrasonic atomizer. Reduction in the splashes and complete elimination of plume were accomplished, while using this new technique. This method could find use in various applications in fields such as medical devices, air filtration, fueling and gas treatment systems.
