Atomization -

As the energy is applied, the liquid first forms sheets or ligaments. These unstable structures eventually collapse into droplets, a phenomenon often described by the Rayleigh-Taylor or Kelvin-Helmholtz instabilities. Critical Applications

Despite its ubiquity, atomization is notoriously difficult to control perfectly. Achieving a "monodisperse" spray—where every droplet is exactly the same size—remains a "holy grail" for engineers. Inconsistent droplet sizes can lead to uneven coating in paint applications or "hot spots" in jet engines. atomization

Using a high-speed stream of air or gas to "tear" the liquid apart. As the energy is applied, the liquid first
