| Реферат: | The article is devoted to a problem of sedimentation of superfine aerosols with a characteristic size of particles, an order of values of micrometers. Acceleration of the sedimentation process is promoted by imposing of an acoustic field that leads to acceleration of coagulation of particles. Besides, pressure of the sound radiation directed down, accelerates gravitational sedimentation of an aerosol. The mathematical model is based on the Smolukhovsky’s equation, describeing dynamics of change of distribution function by the sizes of aerosols particles taking into account ultrasonic influence, evaporation (for liquid aerosols) and sedimentation. Influence of introduction of an additional phase on coagulation and sedimentation speed is investigated. Results of a theoretical and experimental study of dispersion parameters and the sedimentation speed of superfine aerosols are presented. |
