In future Ultra-High By-Pass Ratio turboengines, the turbomachinery noise (fan and turbine
stages mainly) is expected to increase significantly. A review of analytical models and …

A wall-modeled statistically converged Large Eddy Simulation (LES) of the turbulent flow in
the NASA Source Diagnostic Test turbofan has been successfully performed for the first time …

This article deals with the zonal detached eddy simulation of the fan module of a modern
turbofan engine for the prediction of the broadband noise due to the interaction of the fan …

This paper presents undergoing acoustic analyses of an hybrid RANS/LES calculation
performed at ONERA in the framework of an European project TurboNoiseBB. The …

This paper (Part II) presents the broadband noise predictions of a turbofan stage based on a
hybrid method proposed by ONERA in the framework of the European project …

The present article deals with the Zonal Detached Eddy Simulation of the fan module of a
modern turbofan engine. The fan module, tested at the AneCom facility, is equipped with …

Time-resolved simulations present a new opportunity for studying the disturbances
responsible for the broadband interaction noise created by the fan stage. In this paper, two …

Two low-order methods for predicting the broadband noise downstream of a fan exit guide
vane (FEGV) due to interaction with rotor wake turbulence are compared. The noise is …

Rotor-stator interaction (RSI) broadband noise is a subject of growing interest in civil
aviation due to the ever-increasing turbofan bypass ratios. This has positioned the fan and …

La prévision des scénarios de transition laminaire-turbulent, des décollements de couche
limite turbulente et de l'instationnarité des écoulements décollés à grand nombre de …
