A Numerical Method for Extended Boussinesq Shallow-Water Wave Equations
The accurate numerical simulation of wave disturbance within harbours requires consideration of both nonlinear and dispersive wave processes in order to capture such physical effects as wave refraction and diffraction, and nonlinear wave interactions such as the generation of harmonic waves. The …

A numerical method for electro-kinetic flow with deformable interfaces
… time scales are studied both analytically and numerically. We address a significant challenge in the numerical computation of such flows in the thin-double-layer limit, by using the slenderness of the layer to develop a fast and accurate 'hybrid' or multiscale numerical method. The method …

A wave-kinetic numerical method for the propagation of optical waves
A new wave-kinetic numerical method for the propagation of optical waves in weakly inhomogeneous media is discussed, and it is applied to several canonical problems: the propagation of beam and plane waves through a weak 3-D ( or 2-D ) Gaussian eddy. The numerical results are also compared to those …
