The process of low-frequency (up to 130 kHz) cavitational ultrasonic atomization of viscous liquids in a layer with the supplying the acoustic energy via liquid is studied. The mathematical model is proposed and developed to evaluate the optimal modes (frequency and amplitude) and conditions (thickness of the liquid layer) of ultrasound treatment, depending on the physical properties of the liquid (viscosity, surface tension, etc.). The model describes the gradual transformation of the mechanical energy into capillary waves energy that provides the formation of droplets. The results can be used for design of specialized ultrasonic atomizers for viscous liquids.

Key words: ultrasound, atomization, viscous liquids.
