A passive leading-edge treatment based on sinusoidal serrations aimed at reducing
turbofan interaction noise has been recently studied in the framework of a European project …

The aerodynamic noise of the axial compressor is one of the significant noise sources of gas
turbines, and it has gradually attracted the attention of the majority of researchers. In this …

Customer demands for quieter centrifugal fans in the industry have brought their noise to the
forefront. It is found that dipole sources on the surfaces of the rotating impeller and volute are …

The rotor–stator interaction noise in axial fans is mainly caused by the periodic wake from
the rotating fan impinging on the stator rows downstream. In order to accurately predict the …

Tone noise from a rotor–stator system representing a turbofan is studied based on high-
fidelity unsteady simulations. The baseline configuration of the NASA source-diagnostic-test …

The accurate evaluation of the broadband noise generated by fan wakes interacting with the
outlet guide vanes (OGVs) in the aero-engines remains challenging due to the stochastic …

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 …

R= outer radius of the engine's secondary exhaust T= acoustical source period Uexhaust o=
steady mean-field flow, in the exhaust vicinity Uairfoil o= steady mean-flow field, in the airfoil …

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 …

THE noise environment around airports is a major cause of concern worldwide, with many
local communities exposed to high levels of aircraft noise; the effective reduction of such a …
