Homoclinic-shedding in the steady forced water-wave problem
Jack Keeler, Mark Blyth
Recently, an infinite set of steady solitary-wave solution branches was discovered for inviscid and irrotational flow over a localised topographic depression. These solutions were…
The Moffatt-Pukhnachev flow: a new twist on an old problem
Antonio J. Bárcenas-Luque, Mark G. Blyth
The flow of a thin viscous film on the outside of a horizontal circular cylinder, whose angular velocity is time-periodic with specified frequency and amplitude, is investigated. T…
Towards eliminating the nonlinear Kelvin wake
Jack Keeler, Benjamin Binder, Mark Blyth
The nonlinear disturbance caused by a localised forcing moving at constant speed on the free surface of a liquid of finite depth is investigated using the forced Kadometsev-Petvias…
On the stability of fully nonlinear hydraulic-fall solutions to the forced water-wave problem
Jack S. Keeler, Mark G. Blyth
Two-dimensional free-surface flow over localised topography is examined with the emphasis on the stability of hydraulic-fall solutions. A Gaussian topography profile is assumed wit…
