Acoustic oscillations of a gas near nested thin-walled cylindrical obstacles in a channel

The frequencies of eigenoscillations of obstacles axisymmetrically arranged in a channel are found as functions of the obstacle lengths and locations with the use of a mathematical model that describes eigenoscillations of a gas near several thin-walled cylindrical obstacles in a channel. The velocity field and gas density distribution in the channel are found for the first mode of eigenoscillations.
