Abstract

The paper presents the model of influence of acoustic action on the probability of pair collision of the submicron particles and the new method of the action in the shock-wave mode. The model takes into account new non-linear effects of acoustic action in the shock-wave mode for submicron particles. The main effect is changing of uncertainty of the spatial position of the particle due to Brownian motion. The model allowed determining the possibility of the additional efficiency increase of the coagulation in up to 5 times and more at the application of the shock-wave action for the submicron particles in comparison with the sinusoidal action at the similar power consumptions. Under the action of the shock waves superposition generated by the real sources of the shock-wave action (for instance, by multi-frequency radiators forming the alternation of the harmonics of the multiple frequencies, interrupters of the flow, membranes), it is preferable to provide increased duration of the rarefaction wave in comparison with the compression wave. The proposed model can be used as a theoretical base of experimentally observed fact of accelerated coagulation of the submicron particles at the shock-wave action.
