Abstract

Results of research into the evolution of disperse characteristics and concentration of an aerosol during its sedimentation by high-frequency ultrasound, are reported herein. Plots of the aerosol particles concentration versus time are given. The impact of ultrasonic vibrations on a medium-sized aerosol is shown to considerably accelerate its sedimentation due to the particle coagulation. The insertion of an additional dispersed phase (water droplets into a solid-phase aerosol) accelerates the sedimentation as well.
