| Abstract: | 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. |
