A highly adaptive three dimensional hybrid vortex method for inviscid flows and helically symmetric vortex equilibria [PDF]
, 2012 This thesis is concerned with three-dimensional vortex dynamics, in particular the modelling of vortex structures in an inviscid context. We are motivated by the open problem of regularity of the inviscid equations, i.e.

The HyperCASL algorithm: A new approach to the numerical simulation of geophysical flows [PDF]
, 2009 We describe a major extension to the Contour-Advective Semi-Lagrangian (CASL) algorithm (Dritschel & Ambaum 1997, 2006). The extension, called ‘HyperCASL’ (HCASL), uses Lagrangian advection of material potential vorticity contours like CASL, but a Vortex-

The effect of slip length on vortex rebound from a rigid boundary [PDF]
, 2013 The problem of a dipole incident normally on a rigid boundary, for moderate to large Reynolds numbers, has recently been treated numerically using a volume penalisation method by Nguyen van yen, Farge, and Schneider [Phys. Rev.

Modelling vortex-vortex and vortex-boundary interaction [PDF]
, 2010 The motion of two-dimensional inviscid, incompressible fluid with regions of constant vorticity is studied for three classes of geophysically motivated problem. First, equilibria consisting of point vortices located near a vorticity interface generated

Vortical control of forced two-dimensional turbulence [PDF]
, 2013 A new numerical technique for the simulation of forced two-dimensional turbulence (Dritschel and Fontane, 2010) is used to examine the validity of Kraichnan-Batchelor scaling laws at higher Reynolds number than previously accessible with classical pseudo-
