The Weakly-Nonlinear Admittance at Open Ends of Two- and Three-Dimensional Acoustic Waveguides
Freddie Jensen, Harry Turnbull, Edward James Brambley
We formulate a weakly-nonlinear exit condition for open ends of acoustic waveguides; to our knowledge this is the first time a general acoustic open end has been analysed outside t…

Modelling Lateral Spread in Wire Flat Rolling
Mozhdeh Erfanian, Carl D. Slater, Edward James Brambley
A mathematical model for wire rolling is developed, focusing on predicting the lateral spread. This provides, for the first time, an analytic model of lateral spread without any fi…

Multimodal nonlinear acoustics in two- and three-dimensional curved ducts
Freddie Jensen, Edward James Brambley
We develop a weakly nonlinear model of duct acoustics in two and three dimensions (without flow). The work extends the previous work of McTavish & Brambley (2019, J. Fluid Mech. 87…
