COMPUTED MICROTOMOGRAPHIC OBSERVATIONS AND LATTICE- BOLTZMANN SIMULATIONS OF CAPILLARY CHARACTERISTICS

Pore scale considerations are of critical importance for the continued improvement of modeling multiphase ow in porous media at the macroscale. Figure 1: Illustration of the scales at which multiphase ow may be studied. [Gray et al., 2002] Capillary pressure, Pc, is dened as the pressure dierence across the interface that separates two immiscible uids. At the pore scale Pc is dened by Laplace's law
