An empirical model of noise sources in subsonic jets
Ugur Karban, Benjamin Bugeat, Aaron Towne +3
Modelling the noise emitted by turbulent jets is made difficult by their acoustic inefficiency: only a tiny fraction of the near-field turbulent kinetic energy is propagated to the…
Ambiguity in mean-flow-based linear analysis
U. Karban, B. Bugeat, E. Martini +6
Linearisation of the Navier-Stokes equations about the mean of a turbulent flow forms the foundation of popular models for energy amplification and coherent structures, including r…
Using geometric algebra to represent curvature in shell theory with applications to Starling resistors
Alastair L Gregory, Anurag Agarwal, Joan Lasenby
We present a novel application of rotors in geometric algebra to represent the change of curvature tensor, that is used in shell theory as part of the constitutive law. We introduc…
Jet-edge interaction tones
Peter Jordan, Vincent Jaunet, Aaron Towne +4
Motivated by the problem of jet-flap interaction noise, we study the tonal dynamics that occur when a sharp edge is placed in the hydrodynamic nearfield of an isothermal turbulent…
The Elastic Theory of Shells using Geometric Algebra
Alastair Gregory, Joan Lasenby, Anurag Agarwal
We present a novel derivation of the elastic theory of shells. We use the language of Geometric algebra, which allows us to express the fundamental laws in component-free form, thu…
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…
