Kurzfassung
The growing demand of low noise civil aircraft brings out technical challenges which require the application of computational aeroacoustics (CAA) methods within the development process of jet engines. This paper focuses on the simulation of exhaust jet noise based on a realistic turbofan lobe-forced mixer configuration and operating condition. The present study aims at showing the ability of a Ffowcs Williams-Hawkings (FW- H) approach for solving the acoustical sources of a complex turbulent (sheared) flow and for predicting the far field (broadband) noise based on a Detached Eddy Simulation (DES). The evaluation of the prediction results by comparing with benchmark data yield some general guidelines given for model improvements.
