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…
Trapped Free Surface Waves for a Lamb-Oseen Vortex Flow
Emanuele Zuccoli, Edward James Brambley, Dwight Barkley
Trapped surface waves have been observed in a swimming pool trapped by, and rotating around, the cores of vortices. To investigate this effect, we have numerically studied the free…
The critical layer in quadratic flow boundary layers over acoustic linings
Matthew J. King, Edward J. Brambley, Renan Liupekevicius +3
A straight cylindrical duct is considered containing an axial mean flow that is uniform everywhere except within a boundary layer near the wall, which need not be thin. Within this…
Viscous effects on the acoustics and stability of a shear layer over an impedance wall
Doran Khamis, Edward James Brambley
The effect of viscosity and thermal conduction on the acoustics in a shear layer above an impedance wall is investigated numerically and asymptotically by solving the compressible…
