| Abstract: | The article models external flow problems on artificially bounded regions. In the linear approximation we examine the reflection
of acoustic waves in a moving medium, incident at various angles on a fixed boundary. We consider the construction of various
boundary conditions and estimate their reflecting properties for plane waves and waves from point sources. The plane wave
approximation is justified theoretically. A method is proposed for estimating the integral reflection coefficient for waves
with a whole range of incidence angles.
