Nonlinear oscillations of aerosol in open tube in shock-free wave mode at resonance at various amplitudes of excitation are experimentally investigated. Pressure diagrams are continuous. With an increase in the excitation amplitude, the amplitude of the pressure oscillations of the medium increases. At large amplitudes, the oscillation form is close to harmonic. The numerical concentration of aerosol droplets decreases monotonically with time. This is due to the coagulation of the aerosol, which consists in the coalescence of droplets and their sedimentation on the walls of the tube, as well as the emission of the aerosol into the surrounding space. With an increase in the excitation amplitude, the dependences acquire greater curvature and the aerosol clearing time decreases. At the same time, the aerosol clearing time is 5-10 times lower than in the case of natural sedimentation.
