Title

Higher order finite element modeling of acoustic propagation in a moving medium

Abstract

"Stringent noise level requirements for commercial aircraft engines have driven the development of high fidelity numerical methods for the prediction of the noise field in and around turbofan engines. This paper focuses on further development of finite element modeling of acoustic propagation in non-uniform flow within a non-uniform duct characteristic of a turbofan inlet or aft fan duct"--Introduction, page 1.
