Turbulent inertial gelation and acoustic quasi-gelation of submicron aerosol particles

Discrete Smoluchowski equations are investigated for physically similar inertial turbulent and acoustic orthokinetic coagulation of submicron particles. A new scenario of development of gelation is revealed. Turbulent inertial gelation proceeds in the form of a multi-modal relay-type run-away particle size growth including formation of infinite set of secondary maxima in volume fraction distribution. In the case of acoustic quasi-gelation there also exists a run-away particle size growth, characterized, however, by a finite set of secondary maxima points with decay of maximum volumes of the secondary peaks.
