Free surface flow over bottom topography
… solutions with different numbers of waves trapped around the central dip are also found for large amplitude topography but these cannot be captured by the boundary-layer analysis. In fact a seemingly infinite sequence of solution branches is uncovered using numerical methods and a …

An investigation of Lagrangian Riemann methods incorporating material strength
… reference frame to the numerical simulation of non-linear events in solid materials is investigated. Here, solids are characterised by their ability to withstand shear distortion since they possess material strength. In particular, numerical techniques are discussed for simulating the transient …

On the interaction of ocean waves and turbulence
The interaction of ocean waves and turbulence is a fundamental process in the ocean. Understanding and prediction of wind-wave generation, propagation, breaking, non-linear interactions and extreme wave development are directly linked to this complex and not well understood phenomenon (Thorpe …

Spherically-symmetric inhomogeneities in general relativity and their effects in cosmology
… to the LTB model, naturally accommodates non-zero pressure and has a more transparent physical interpretation. Next we apply the tetrad-based method to a generalised form of `Swiss cheese' model, which consists of an interior spherical region surrounded by a spherical shell of vacuum that …
