Abstract:

The oscillating motion and drift of an aerosol particle in a gas under the action of a sound field are studied at the arbitrary Knudsen numbers. The relaxation time, the flow coefficient, the phase shift of gas and particle oscillations and the drift velocity are calculated as functions of Knudsen number and the sound wave frequency. It is shown that the drift velocity of aerosol particles can change its direction at the intermediate Knudsen numbers.
