Abstract: Aerosol technologies often require increasing the dispersion of droplets already present in the air. We proposed a mathematical model and investigated the mechanisms of ultrasonic cavitation fragmentation of aerosol droplets. Expressions for the minimum radiation pressure required for fragmentation of droplets were obtained.

Keywords: aerosol, ultrasound, cavitation, fragmentation.
