Sound propagation in slowly varying 2D duct with shear flow

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review

Abstract

A slowly varying modes solution of WKB type is derived for the problem of sound propagation in a slowly varying 2D duct with linearly sheared mean flow. Both the slowly varying mean flow equations and the Pridmore-Brown equation for the modes can be solved analytically exactly.
