Optimal transient growth in thin-interface internal solitary waves [PDF]

open access: yes, 2017
The dynamics of perturbations to large-amplitude Internal Solitary Waves (ISW) in two-layered flows with thin interfaces is analyzed by means of linear optimal transient growth methods. Optimal perturbations are computed through direct-adjoint iterations

Tsunami generation by paddle motion and its interaction with a beach: Lagrangian modelling and experiment [PDF]

open access: yes, 2013
A 2D Lagrangian numerical wave model is presented and validated against a set of physical wave-flume experiments on interaction of tsunami waves with a sloping beach. An iterative methodology is proposed and applied for experimental generation of tsunami-

An intrusion layer in stationary incompressible fluids Part 2: A solitary wave [PDF]

open access: yes, 2006
The propagation of a solitary wave in a horizontal fluid layer is studied. There is an interfacial free surface above and below this intrusion layer, which is moving at constant speed through a stationary density-stratified fluid system.

Numerical study of nonlinear shallow water waves produced by a submerged moving disturbance in viscous flow [PDF]

open access: yes, 1996
Two-dimensional solitary waves generated by a submerged body moving near the critical speed in a shallow water channel are studied numerically. The incompressible Navier–Stokes equations in a curvilinear free-surface-fitted coordinate system are solved ...

Time dependent hydraulic falls and trapped waves over submerged obstructions [PDF]

open access: yes, 2014
We consider the classical problem of a free surface flowing past one or more disturbances in a channel. The fluid is assumed to be inviscid and incompressible, and the flow, irrotational.

Frequency dispersion of small-amplitude capillary waves in viscous fluids [PDF]

open access: yes, 2016
This work presents a detailed study of the dispersion of capillary waves with small amplitude in viscous fluids using an analytically derived solution to the initial value problem of a small-amplitude capillary wave as well as direct numerical simulation.

Large-amplitude capillary waves in electrified fluid sheets [PDF]

open access: yes, 2004
Large-amplitude capillary waves on fluid sheets are computed in the presence of a uniform electric field acting in a direction parallel to the undisturbed configuration. The fluid is taken to be inviscid, incompressible and non-conducting.

On solitary waves forced by underwater moving objects [PDF]

open access: yes, 1999
The phenomenon of a succession of upstream-advancing solitary waves generated by underwater disturbances moving steadily with a transcritical velocity in two- dimensional shallow water channels is investigated.

Classification of instabilities in parallel two-phase flow [PDF]

open access: yes, 1996
There is extensive literature on the stability of parallel two-phase flow, both in the context of liquid-liquid as well as gas-liquid flow. Aimed at making this literature more transparent, this paper presents a classification,scheme for the various ...
