Unstetige Galerkin-Diskretisierung niedriger Ordnung in einem atmosphärischen Multiskalenmodell
… der atmosphärischen Dynamik mit Euler- und Flachwassergleichungen in einem weiten Bereich von räumlichen und zeitlichen Skalen. Die Lösung der thermischen Windgleichung entlang der mit den Isobaren identischen charakteristischen Kurven liefert atmosphärische Gleichgewichtszustände mit durch …

Die Runge-Kutta-Discontinuous-Galerkin-Methode zur Lösung konvektionsdominierter tiefengemittelter Flachwasserprobleme
Advances in Computational Fluid Dynamics are only to some extend related to rapidly increasing computer performance, but also to improvement of governing equations and numerical solution algorithms. The focus of this thesis is the numerical solution of the two-dimensional depth-averaged shallow …

High-order well-balanced finite volume schemes for geophysical flows : development and numerical comparisons
Many geophysical flows are merely perturbations of some fundamental equilibrium state. If a numerical scheme shall capture such flows efficiently, it should be able to preserve the unperturbed equilibrium state at the discrete level. In the first part of this thesis we present a class of schemes of …
