Achieving Optimal Locomotion using Self-Generated Waves
D. O'Donovan, M. D. Bustamante, O. Devauchelle +1
An oscillating body floating at the water surface produces a wave-field of self-generated waves. When the oscillation induces a difference in fore-aft wave amplitude squared, these…
On wave-driven propulsion
GP Benham, O Devauchelle, SJ Thomson
A theory is presented for wave-driven propulsion of floating bodies driven into oscillation at the fluid interface. By coupling the equations of motion of the body to a quasi-poten…
Anisotropy distorts the spreading of a fixed volume porous gravity current
GP Benham
We consider the release and subsequent gravity-driven spreading of a finite volume of fluid in an anisotropic porous medium bounded by an impermeable substrate. When the permeabili…
The near-field shape and stability of a porous plume
GP Benham
When a fluid is injected into a porous medium saturated with an ambient fluid of a greater density, the injected fluid forms a plume that rises upwards due to buoyancy. In the near…
Axisymmetric gravity currents in anisotropic porous media
GP Benham, JA Neufeld, AW Woods
We explore the motion of an axisymmetric gravity current in an anisotropic porous medium in which the horizontal permeability is larger than the vertical permeability. It is well k…
Two-phase gravity currents in layered porous media
GP Benham, MJ Bickle, JA Neufeld
We examine the effects of horizontally layered heterogeneities on the spreading of two-phase gravity currents in a porous medium, with application to numerous environmental flows,…
