Formation of jet atomization using a steel plate vibrated by weakly coupled ultrasonic transducer through water

摘要

This paper demonstrates the formation and control of jet atomization by inserting a steel plate into distilled water on an ultrasonic transducer. The direction of jet atomization was perpendicular to the vibration direction of the transducer, and inserting a steel plate succeeded in generating jet atomization in a direction different from the vibration direction of the transducer. This study also revealed that the amount of atomization can be adjusted; atomization was generated evenly from both sides of the plate at a rate of 1.77 mg s(-1) when the plate was set at the center of the transducer, and it was generated from only one side of the plate at a rate of 1.5 mg s(-1) when the plate was shifted 2 mm from the center of the transducer. The techniques developed in this study will greatly contribute to the fields of engineering, medicine, and sonochemistry, wherein various atomization controls are desired.
