Abstract
Provided is a liquid droplet generation method capable of generating liquid droplets having a diameter of 100 μm or more. The liquid droplet generation method for generating liquid droplets from a liquid layer 20 by using a plurality of transducers 18, the method including irradiating the liquid layer 20 with a plurality of ultrasonic waves from the plurality of transducers 18 to scatter primary liquid droplets 21A and 21B from the liquid layer 20, and causing the primary liquid droplets 21A and 21B being scattered to aggregate and grow into a secondary liquid droplet 22A.
Claims2
A liquid droplet generation method for generating liquid droplets from a liquid layer by using a plurality of transducers, the method comprising:
- irradiating the liquid layer with a plurality of ultrasonic waves from the plurality of transducers to scatter a plurality of primary liquid droplets from the liquid layer;
- causing the plurality of primary liquid droplets being scattered to aggregate and grow into a secondary liquid droplet;
- and
- wherein a signal application time for each of the plurality of transducers is 10 ms or more.
A liquid droplet generation method for generating liquid droplets from a liquid layer by using a plurality of transducers, the method comprising:
