Numerical analysis of acoustic spectral problems for three-dimensional domains with stationary flow an acoustic absorption of walls

摘要

The proposed approach based on the inverse iteration method is intended to study eigenforms and frequencics of the acoustic gas oscillations in regions of complex spatial form usin gthe 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.
