A free-surface-only closure model for linear waves on general deep-water flows
Emanuele Zuccoli, Edward James Brambley, Dwight Barkley
We present a novel, spatially two-dimensional (2D) set of equations to study the propagation of linear deep-water surface waves over a general steady three-dimensional (3D) backgro…
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…
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…
