Gas and Aerosol Resonance Oscillations in an Open Pipe with an Abrupt Change in Cross Section
Abstract
Gas oscillations and aerosol dynamics at a resonance frequency in an open pipe with a changing cross section have been studied. The dependences of the amplitude of gas pressure oscillations and the time of aerosol deposition were obtained for different amplitudes of piston displacement at resonance. The presence of a changing cross section made it possible to obtain more intense oscillations as compared to a homogeneous pipe, while the shape of the pressure wave remained continuous and close to harmonic for all considered excitation amplitudes. A decrease in the concentration of aerosol droplets over time was revealed, accelerating with increasing amplitude of piston displacement.
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.
