Abstract: Techniques including methods, apparatus and computer program products are disclosed. These techniques include computer instructions that are encoded on computer storage media for determining wettability. The techniques use a numerical aging computation process to provide a representation of a wettability alteration of a physical rock sample in the presence of at least two fluids is disclosed. The techniques include retrieving a representation of a physical rock sample, the representation including pore space and grain space data corresponding to the physical rock sample, calculating local curvature for each surface in the pore space, determining from the calculated local curvature whether water-film breakage will occur, and classifying the wettability of the physical rock based on the determination of water-film breakage.

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.
