The present paper is aimed at providing an updated review of prediction methods for the
aerodynamic noise of ducted rotor–stator stages. Indeed, ducted rotating-blade technologies …

This study aims at evaluating previously designed leading edge serrations for the turbulence-
cascade interaction noise reduction on a rectilinear cascade. Low and high-fidelity …

A numerical study is carried out to assess the aerodynamic and noise radiation specific
features of the ACAT1 fan stage, which was tested in the framework of the European project …

A scale model of a fan stage operating at approach condition is investigated using wall-
resolved Large Eddy Simulations. The configuration is a state-of-the-art fan stage (rotor+ …

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 …

The shear stress transport turbulence model is employed to conduct a detailed study of flow
characteristics at the highest efficiency point and near-stall point in a full-channel 1.5-stage …

Tip-clearance (TC) noise is significant in compressors and has garnered scholarly attention
for the isolated rotor. However, applying these findings to marine compressors with rotor …

Flow separations occur in the tip region when the fan is operating at the approach condition.
To reduce computational cost without degrading accuracy, the hierarchical modeling …

This work is devoted to the design and evaluation of a low-noise OGV aiming to reduce the
rotor-stator interaction noise using leading edge serrations and tested on the ECL5 UHBR …
