Wave dynamics of gas suspensions and individual particles during resonance oscillations

We review here the results of experimental and theoretical studies on the dynamics of gas suspensions and individual particles in wave fields of resonators of various shapes. The effects of the coagulation and sedimentation of aerosols of various natures under acoustic and shock-wave impacts, as well as the patterns of the trapping, focusing, and separation of particles in wave fields, are considered. The main forces leading to the drift of particles in the wave field, as well as the effect of acoustic streaming, are discussed.
