Simulation of two-phase incompressible fluid flow in highly heterogeneous porous media by considering localization assumption in multiscale finite volume method

作者:

Highlights:

• Six localization schemes producing basis functions for the MsFV method are compared.

• Localization schemes are presented in both classic and matrix formulations.

• A heterogeneous two-dimensional problem with a continuous permeability field is designed and solved analytically.

• The accuracy of MsFV with different localizations is examined for highly heterogeneous problems.

• The modified variable boundary condition produces the most accurate results, among the considered localization schemes.
