Geometric algebra and an acoustic space time for propagation in non-uniform flow
Alastair Gregory, Anurag Agarwal, Joan Lasenby +1
This study aims to make use of two concepts in the field of aeroacoustics; an analogy with relativity, and Geometric Algebra. The analogy with relativity has been investigated in p…
An integral formulation for wave propagation on weakly non-uniform potential flows
Simone Mancini, R. Jeremy Astley, Samuel Sinayoko +2
An integral formulation for acoustic radiation in moving flows is presented. It is based on a potential formulation for acoustic radiation on weakly non-uniform subsonic mean flows…
Prediction of noise from serrated trailing-edges
B. Lyu, M. Azarpeyvand, S. Sinayoko
A new analytical model is developed for the prediction of noise from serrated trailing-edges. The model generalizes Amiet's trailing-edge noise theory to sawtooth trailing-edges, r…
An acoustic space-time and the Lorentz transformation in aeroacoustics
Alastair Logan Gregory, Samuel Sinayoko, Anurag Agarwal +1
In this paper we introduce concepts from relativity and geometric algebra to aeroacoustics. We do this using an acoustic space-time transformation within the framework of sound pro…
On wavenumber spectra for sound within subsonic jets
S. Sinayoko, A. Agarwal, R. D. Sandberg
This paper clarifies the nature of sound spectra within subsonic jets. Three problems, of increasing complexity, are presented. Firstly, a point source is placed in a two-dimension…
Trailing edge noise theory for rotating blades in uniform flow
Samuel Sinayoko, Mike Kingan, Anurag Agarwal
This paper presents a new formulation for trailing edge noise radiation from rotating blades based on an analytical solution of the convective wave equation. It accounts for distri…
