摘要

摘要本文通过实验研究了具有横截面跃迁的开口管中气体和气溶胶的强迫纵向振荡。与均质管相比，截面跃迁管中气体振荡加剧，而压力波形仍接近谐波和连续。发现气溶胶沉积时间与振荡频率呈非单调依赖关系，在共振频率下数值最小。

Forced Longitudinal Oscillations of Gas and Aerosol in an Open Tube with a Cross-Sectional Jump

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.

期刊介绍： Doklady Physics is a journal that publishes new research in physics of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
