Sound radiation from a lined exhaust duct with lined afterbody

A. Demir, S.W. Rienstra

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


Aft fan noise radiating from a lined bypass exhaust duct with lined afterbody is modelled in a way that allows an analytical solution of generalised Wiener-Hopf type. A preliminary set of numerically evaluated examples, based on the experiments by Tester at al. seem to confirm their conclusions that the beneficial effect of a lined afterbody is mainly found without mean flow.
