A new method of liquid atomization into submicron droplets has been invented.
The method includes production and disintegration of thin liquid films by gas jets.
Tap water droplets with Sauter diameters 2.66–7.53 µm were produced in experiments.
Formation of bubbles, froth and “micro-sprays” of droplets was directly observed.
The new method is scalable, simple and low cost, and suitable for different liquids.
