| Zusammenfassung |
| An integrated method of advanced anisotropic hr-adaptive mesh and
discretization numerical techniques has been, for first time, applied to
modelling of multiscale advection–diffusion problems, which is based on a
discontinuous Galerkin/control volume discretization on unstructured meshes.
Over existing air quality models typically based on static-structured grids
using a locally nesting technique, the advantage of the anisotropic
hr-adaptive model has the ability to adapt the mesh according to the evolving
pollutant distribution and flow features. That is, the mesh resolution can be
adjusted dynamically to simulate the pollutant transport process accurately
and effectively. To illustrate the capability of the anisotropic adaptive
unstructured mesh model, three benchmark numerical experiments have been
set up for two-dimensional (2-D) advection phenomena. Comparisons have been
made between the results obtained using uniform resolution meshes and
anisotropic adaptive resolution meshes. Performance achieved in 3-D simulation
of power plant plumes indicates that this new adaptive multiscale model has
the potential to provide accurate air quality modelling solutions effectively. |
