High resolution methods for incompressible, compressible and variable density flows.
The uid dynamics community has dealt with a number of numerical challenges since the 1950's. These include the development of numerical methods for hyperbolic conservation laws with particular interest in capturing shock wave propagation and related ...

A highly adaptive three dimensional hybrid vortex method for inviscid flows and helically symmetric vortex equilibria [PDF]
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.

An intrusion layer in stationary incompressible fluids: Part 1: Periodic waves [PDF]
Waves on a neutrally buoyant intrusion layer moving into otherwise stationary fluid are studied. There are two interfacial free surfaces, above and below the moving layer, and a train of waves is present.
