Interaction sprayed of charge fine powders with electroneutral liquid-phase and solid-phase aerosol environments

Abstract

In work the interaction of a solid-phase fine aerosol cloud of charged par-ticlesatomized by means of the electrostatic spray with the liquid-phase and solid-phase weighed particles aerosol created in the pulse and pneumatic way is considered. Each method of dispersion allows to form a stream of the condensed particles for modeling real situations of formation of the harmful fine aerosol environments arising at accidents on the industry, extraordinary natural cataclysms, acts of terrorism, conducting military operations, etc. Introduction of charged particles to a neutral stream of a harmful aerosol causes the phenomenon of electrostatic coagulation, accelerating process sedimentation of such aerosol. For the purpose of determination of speed of sedimentation due to emergence of effect of electrostatic coagulation the pilot studies allowing to estimate change of dispersion and concentration of fine aerosol environments in the closed volume are conducted. Observation of emergence and development of coagulative processes in aerosols the laser measuring LID-2M complex was used. In the LID-2M installation the modification of an optical method of low-angle dispersion connected with the solution of a series of direct problems of optics of aerosols in a task about dispersion of a laser beam the disperse environment under small corners is realized.
