Abstract

Nonlinear oscillations of a gas and deposition of tobacco smoke at resonance in a narrow closed tube were experimentally studied. The resulting oscillograms show asymmetry of the leading and trailing edges of the pressure wave. With an increase in piston oscillation amplitude, an increase in the sound pressure level of the gas was revealed to 163 dB at a maximum studied excitation amplitude of 0.3 mm. The deposition of tobacco smoke particles in resonance oscillation mode with an excitation amplitude of 0.3 mm occurs 24 times faster compared to natural deposition.

共振振荡模式下多分散气溶胶在窄封闭管中的沉积

摘要通过实验研究了气体的非线性振荡和烟草烟雾在狭窄封闭管道中的共振沉积。振荡图显示压力波的前缘和后缘不对称。随着活塞振荡振幅的增大，气体的声压级增加到 163 分贝，最大激振振幅为 0.3 毫米。在激励振幅为 0.3 毫米的共振振荡模式下，烟草烟雾颗粒的沉积速度是自然沉积速度的 24 倍。

期刊介绍： High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
