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…
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 without mean flow; to our knowledge this is the first time an acoustic open end has been analyse…
Through-Thickness Modelling of Metal Rolling using Multiple-Scale Asymptotics
Mozhdeh Erfanian, Edward James Brambley, Francis Flanagan +2
A new semi-analytic model of the metal rolling process is introduced, which, for the first time, is able to predict the through-thickness stress and strain oscillations present in…
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…
A deep-water closure model for surface waves on axisymmetric swirling flows
Emanuele Zuccoli, Edward James Brambley, Dwight Barkley
We consider the propagation of linear gravity waves on the free surface of steady, axisymmetric flows with purely azimuthal velocity. We propose a two-dimensional set of governing…
