OPTICAL MEASUREMENTS OF THE PRECIPITATION OF AN AEROSOL UNDER THE INFLUENCE OF EXTERNAL PHYSICAL FIELDS

摘要

Results of experimental investigation of the evolution and precipitation of a cloud of pneumatically obtained aerosol particles in a closed space under the influence of external physical fields are presented. The precipitation is contributed to by imposing acoustic and electrostatic fields, which leads to an acceleration of the coagulation of fine-aerosol particles. A method of searching for the aerosol's dispersion characteristics is proposed, which has been implemented in a laser measuring complex. Experimental dependences of the average volume-surface diameter and of the relative concentration of aerosol particles of a model aerosol (talc) on time are presented.
