| Abstract: | Acoustic eigenoscillations of a gas near a plate in a rectangular channel, i.e., the eigenfrequency of oscillations as a function
of the chord length and the position of the plate in the channel, and the form of the eigenfunctions are studied in a two-dimensional
formulation. A mathematical model of eigenoscillations near a plate in a channel has been proposed and substantiated, and
the dependence of the eigenfrequency of oscillations on the geometric parameters is studied numerically with the use of this
model.
