| Zusammenfassung |
| Pore scale simulations of multi phase flow in porous media present a promising approach
in the development and verification of continuum scale models as well as in the
understanding of the underlying processes of flow phenomena like hysteresis or the
peculiarities of the capillary fringe. As typical pore geometries involve complicated
geometries with peculiar topological properties, the generation of a computational mesh,
required by finite element (FE) based simulation approaches, becomes a limiting
obstacle.
We present a numerical discretization based on discontinuous Galerkin methods which
does not require a grid which is fitted to the computational domain. In this approach, the
resolution of the domain boundaries may be chosen independent of the FE basis.
Furthermore, we will present discretization techniques allowing for an accurate
representation of the interface conditions i.e. the jump in the pressure and the velocity
derivatives. First results of simulations for two-phase flow in pore geometries are discussed. |
