Large Eddy Simulation and Direct Noise Prediction of a Fan Stage in Transonic Regime

Résumé

The broadband noise generated within a fan-OGV stage and partly caused by the interaction between shockwaves and turbulent structures cannot be easily modelled due to the stochastic nature of the flow. High fidelity numerical methods are able to simulate with sufficient accuracy the characteristics of the flow. LES of the ECL5 fan/OGV stage are performed using the AVBP solver developed by CERFACS. The purpose of those simulations is to locate and characterize broadband noise sources.
