oa Macrodispersion Approach for Upscaling of Two-Phase, Immiscible Flow in Heterogeneous Porous Media

This paper focuses on upscaling of immiscible flow in porous media. It is currently admitted that classical pseudoization methods suffer lome limitations, mainly due to the fact that numerical and physical coarsening are coupled within this framework. In order to overcome this problem, we look at the analytical form of upscaled transport equations, reserving the grid blocks coarsening to a subsequent step.
