"Spatial approximation by the subgrid method in the filtration
problem for a viscous compressible fluid in a porous medium" Bogachev K.Yu., Melnichenko N.S. |
|
The filtration problem for a viscous compressible multiphase fluid mixture
in an anisotropic porous medium is considered. For this problem, the spatial
approximation is discussed in the case of nonorthogonal unstructured grids.
A new method of multipoint approximation is proposed. This method is free
from the following defects of other similar methods: the orientation effect
and the appearance of nonphysical fluxes. Some numerical results obtained
on the basis of realistic problems are given.
