The search for physical effects that contribute to the compaction of the cloud of aerosol particles is an urgent task. An analysis of nonlinear physical phenomena that occur during the formation of an acoustic field made it possible to establish that vortex acoustic flows turn out to be a significant factor in resonant oscillations of the gas gap, which, due to inertia forces, can cause local compaction of the aerosol cloud. A model similar to the discrete phase approach is proposed, which is capable of calculating the motion of an aerosol cloud. The possibility of a local increase in concentration by more than 2 times when exposed to a resonant air gap has been proven. It has been established that the maximum concentration of the aerosol cloud is achieved in areas with the maximum sound pressure level, which additionally contributes to an increase in the efficiency of coagulation. However, the maximum achievable degree of increase in concentration in the range of sound pressure levels from 150 to 155 dB decreases with increasing level. At the same time, with an increase in the level of sound pressure, the time to reach the maximum increase in concentration is reduced and, as is known, the efficiency of coagulation increases. This indicates the need to find the optimal sound pressure level for coagulation in the air gap. [ABSTRACT FROM AUTHOR] |
