AB: A parallel processing version of the 3D Shan-and-Chen (SC) multi-component, multiphase lattice Boltzmann method (LBM) was developed and used to simulate the distributions of two immiscible fluids in porous media. The model was tested for conformance to the laws of Laplace (fluid-fluid interfacial tension) and Young (contact angles). Then, the SC LBM was successfully validated against cone beam X-ray microtomographic data for the distribution of oil (decane), water, and air phases in a 5-mm cube of porous medium composed of packed quartz sand grains. The results confirm that LBM models allow for the straightforward incorporation of complex pore space geometry as defined from X-ray microtomography measurements and that simulated wetting and non-wetting phase distributions are consistent with X-ray observations on both macroscopic and microscopic scales.
