Abstract:

Changes in pore scale geometry cascade into changes in the critical core scale coefficients, porosity and permeability. With numerical upscaling, we move information from pore scale to core scale. In this talk, we describe two novel methods for generating realistic obstructions to pore scale flow; a Markov Chain Monte Carlo (MCMC) method and another based on phase separation dynamics. With these numerically inexpensive methods we can build large classes of obstructed pore scale geometries, which are used in generating the permeability density functions for a given class of obstructions.
