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 …

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 …

The present work describes a numerical reproduction of the 22-in source diagnostic test fan
rig of the NASA Glenn Research Center. Numerical flow simulations are performed for three …

The fan noise in the train electric traction system contributes to the main noise of the train,
affecting the comfort of the passengers. The prediction of fan noise can serve as a …

The present paper deals with the assessment of the turbulent flow through and the noise
radiation of the ACAT1 fan stage, which was tested in the framework of the European project …

A benchmark dedicated to RANS-informed analytical methods for the prediction of turbofan
rotor–stator interaction broadband noise was organised within the framework of the …

In order to meet noise specifications for future foreseen aircraft propulsion systems, such as
for ultrahigh bypass ratio turbofans and contra-rotating open rotors, the dominant …

The fan broadband noise of a rotor–stator system representing a turbofan aeroengine is
investigated using the improved delayed detached-eddy-simulation approach. The baseline …

Abstract Fan/Outlet-Guide-Vane (OGV) interaction is a major broadband noise source in
high bypass ratio turbofan engines. This paper assesses the acoustic shielding created by …

Abstract Rotor–Stator Interaction (RSI) noise predictions using analytical models have
become a first hand approach to perform quick and efficient noise assessments. However, a …
