Study of Acoustic Noise during Gas Filtration through a Porous Medium

Study of Acoustic Noise during Gas Filtration through a Porous Medium Abstract— As fluids and gases move through porous media, they generate acoustic noise. It is shown that the shape of the noise spectra is determined by the properties of the fluid and the porous reservoir, as well as by the flow regime. Our study has experimentally confirmed the conclusions that the location of sound intensity maxima are independent of the rate of fluid filtration through a porous medium. The criterion for the occurrence of filtration noise as a fluid moves through a porous medium is determined. The dependence of the sound intensity maximum on the fluid filtration rate is studied. The relationship between the porosity and permeability of porous media samples and the character of the filtration noise spectra is considered. The obtained experimental data can be used to create a sound generation model for gas filtration through a porous medium. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acoustical Physics Springer Journals

Abstract

Abstract— As fluids and gases move through porous media, they generate acoustic noise. It is shown that the shape of the noise spectra is determined by the properties of the fluid and the porous reservoir, as well as by the flow regime. Our study has experimentally confirmed the conclusions that the location of sound intensity maxima are independent of the rate of fluid filtration through a porous medium. The criterion for the occurrence of filtration noise as a fluid moves through a porous medium is determined. The dependence of the sound intensity maximum on the fluid filtration rate is studied. The relationship between the porosity and permeability of porous media samples and the character of the filtration noise spectra is considered. The obtained experimental data can be used to create a sound generation model for gas filtration through a porous medium.
