Beschreibung
Zusammenfassung:	In this paper, we study experimentally the forced longitudinal oscillations of gas and aerosol in an open tube with a cross-sectional jump. An intensification of gas oscillations in a tube with a cross-sectional jump in comparison with a homogeneous tube, while the pressure waveform remains close to harmonic and continuous, is observed. A nonmonotonic dependence of the aerosol deposition time on the oscillation frequency with a minimal value at the resonant frequency was discovered.
