An analytical model is developed for the prediction of noise radiated by an aerofoil with
leading-edge serration in a subsonic turbulent stream. The model makes use of Fourier …

COMPUTATIONALLY it is inefficient, and as yet practically impossible, to describe the sound
field that is produced within a turbofan aeroengine duct, by rotor–stator interaction of fan and …

The sound generated by the interaction between a turbulent rotor wake and a stator is
modelled by considering the gust response of a cascade of blades in non-uniform, subsonic …

An experimental investigation into the response of an airfoil in turbulence is undertaken and
the results are presented in a two part series of papers. The effects of mean loading on the …

In this paper we consider the propagation of acoustic waves on top of an inviscid steady flow
along a curved hollow or annular duct with hard or lined walls. The curvature of the duct …

A theoretical model is developed for the sound scattered when a sound wave is incident on
a cambered aerofoil at non-zero angle of attack. The model is based on the linearization of …

The unsteady lift forces that act on an airfoil in turbulent flow are an undesirable source of
vibration and noise in many industrial applications. Methods to predict these forces have …

This paper presents an experimental study to characterise the effect of inflow disturbance on
the noise emanating from a two-bladed 12x6 in. drone propeller. To simulate the cruising …

This dissertation presents measurements of unsteady surface pressure on airfoils
encountering flow disturbances. Analysis of measurements made on an airfoil immersed in …

Gust/turbulence–leading edge interaction is a significant source of airfoil broadband noise.
An approach often used to predict the sound is based on Amiet's flat-plate solution …
