摘要：

The formation of a microatomized aerosol was investigated with the use of a model of an explosion atomizer based on a hydrodynamic shock tube with atomization through a clearance (nozzle). It is shown that the cavitation of the liquid subjected to atomization plays a great role in the production of a microatomized liquid- drop aerosol. A mathematical model describing the genesis of an aerosol cloud is proposed. The time of propagation of a compression wave in the liquid subjected to atomization and the time of its outflow from the atomizer were estimated, the size distribution of the aerosol particles was constructed, and the dependence of this distribution on the coagulation, evaporation, and precipitation of the aerosol particles was determined. A technique for undisturbed measurement of the genesis of an aerosol is described. Results of an experimental investigation of the dispersion parameters of an aerosol and the processes of formation and propagation of an aerosol cloud produced as a result of the explosion atomization of a liquid are presented. © 2010 Springer Science+Business Media, Inc.
