- •
The potential use of high-intensity ultrasound fields in gaseous atmosphere to disperse agglomerated particles is studied.
- •
Trajectories of levitating agglomerates are derived and the motion behavior is characterized.
- •
Breakage probabilities are derived depending on the mass specific breakage energy of individual agglomerates.
- •
Relevant parameters for particle adhesion were varied in order to investigate their effect on the breakage probability.
- •
Results are compared to analytical equations for acoustic radiation pressure and adhesion forces.
