| Abstract |
The reflection and transmission of harmonic waves and waves of finite duration through the boundary of the perforated part of a cylindrical channel (a lined borehole), filled with a fluid and surrounded by a permeable porous medium, is investigated. A model of the plane time-varying fluid flow in the cylindrical channel in a quasi-one-dimensional approximation and of the seepage absorption of the fluid in the porous medium surrounding the channel is presented. The effect of the collector characteristics of the porous medium surrounding the channel and the quality of the perforation (the length of the perforation channels) on the evolution of the waves when they are reflected from the boundary of the perforated part of the wall are investigated. |
