Modelling the Dynamics of Turbulent Floods

Consider the dynamics of turbulent flow in rivers, estuaries and floods. Based on the widely used k-ǫ model for turbulence, we use the techniques of centre manifold theory to derive dynamical models for the evolution of the water depth and of vertically averaged flow velocity and turbulent parameters. This new model for the shallow water dynamics of turbulent flow: resolves the vertical structu...

Numerical Modelling of Viscous and Turbulent Free-surface Flows Using Smoothed Particle Hydrodynamics

This thesis presents the formulation of a Smoothed Particle Hydrodynamics (SPH) model and its application to a range of engineering applications. The motivation for this research lies in the desire to accurately model viscous and turbulent free-surface flows, including those with complete break-up of the free-surface. At present, boundary element modelling is typically chosen to describe free-s...

Numerical experiments of the formation of dwarf galaxies using Smoothed Particle Hydrodynamics Method

Three-dimensional N-body/hydrodynamical simulations of the formation and evolution of dwarf galaxies are presented in the cosmologically motivated initial conditions. The calculation including gas dynamics, dark matter, radiation processes, star formation, supernovae and stellar winds feedback, and metal enrichment reproduces reasonably well both the exponential radial luminosity pro les and th...
