Abstract: A method analyzes physical transport in a proton exchange membrane fuel cell (PEMFC) having three adjacent layers L1, L2, L3, each with a distinct porous structure. A first small scale multiphase simulation S1 of a first portion of the L1/L2 interface is used to characterize the L1/L2 interface. The S1 results are statistically extended to a larger second portion of the L1/L2 interface. The statistically extended L1/L2 interface is used as a boundary condition for a second multiphase simulation S2 to characterize the L2/L3 interface. S1 is repeated using the characterized L2/L3 interface as a boundary condition. S1 and S2 respectively simulate of one or more of momentum, energy, species, and charge transport across the L1/L2 and L2/L3 interface.

Abstract: Disclosed are computer implemented techniques for conducting a fluid simulation of a porous medium. These techniques involve retrieving a representation of a three dimensional porous medium, the representation including pore space corresponding to the porous medium, with the representation including at least one portion of under-resolved pore structure in the porous medium, defining a representative flow model that includes the under-resolved pore structure in the representation, and constructing by the computer system fluid force curves that correspond to fluid forces in the under-resolved pore structure in the representation.
