Abstract

The proposed approach based on the inverse iteration method is intended to study eigenforms and frequencies of the acoustic gas oscillations in regions of complex spatial form using the geometrical immersion method on each iteration. It permits us to reduce the problem of acoustic oscillations in three dimensional domain to a converging sequence of problems in the canonical domain involving the initial one. The approach has been developed to solve the problem on spectral gas properties in a chamber, taking into account stationary flows and acoustic conductivity of the region boundaries. The numerical results, obtained for a tube with the cross-section
