Abstract :
The mathematical model of the process on the macroscopic level considering viscosity of gas medium has been proposed for the analysis of acoustic coagulation of solid and fluid particles in gas media. The article presents the results of theoretical calculations, which allow determining the dependences of coagulation velocity at the different initial particle concentration on the parameters of acoustic influence (intensity, frequency). As a result of the investigation high efficiency of application of acoustic vibrations with the frequencies lying in the ultrasonic range for coagulation of fine aerosol (up to 5 μm) is shown.
