DFG FG 581 Natural Slopes: Coupling of Flow and Deformation Processes for Modeling the Movement of Natural Slopes, Karlsruhe, Almanya, 27 - 28 Mart 2008, ss.12
Many flow problems in environmental, technical and biological systems are characterized by a distinct interaction between a flow region in porous medium and a
pipe flow region in quasi-one-dimensional hollow structures. Examples for such systems are (i)mines: Methane released from unmined coal seams migrates through the
porous rocks, but also through tunnels and shafts in the mine. (ii) Landslides: A
sudden water infiltration through macropores may trigger landslides. (iii)Polymer
electrolyte membrane fuel cells: The supply of reactive gases through free-flow channels into the porous diffusion layers interacts strongly with the evacuation process
of the water, which is formed at the cathode reaction layer and flows from the
porous diffusion layers into the free-flow channels. (iv) Cancer therapy: Therapeutic agents are delivered via the blood vessels into the tissue, targeting the tumor
cells. In this work a dual-continuum strategy, for the simulation of coupled porous
media flow with lower-dimensional pipe flow will be presented. For the numerical
implementation a special grid called 1D pipe network grid in a 3D porous grid is
developed.
