内容摘要:

Porous media flow is central to a wide range of natural and engineered processes, including water infiltration into soil, geologic carbon sequestration, enhanced oil recovery, and geothermal energy extraction. Darcy-scale flow simulation has routinely used by reservoir engineers over half a century, but more recently (say, 20 years), digital Rock Physics (DRP) and pore-scale flow simulation is getting popular as non-destructive methods used to determine absolute/relative permeability, capillarity, effective elastic rock parameters and other porous media properties. In this talk, we share a few of our recent works in digital rock physics and pore-scale flow simulation, including 1) our research on the two-scale molecular dynamics–Monte Carlo algorithm with applications in pore-scale phenomena; 2) our ongoing research on unconditionally stable scheme of Lattice Boltzmann method (LBM); 3) our novel SPH-based particle method for pore-scale flow simulation, which preserves not only mass, momentum but also energy dissipation law in the discrete solution; and 4) the pore-network model described from model reduction viewpoint for pore-scale fluid flow as well as our new pixel-free algorithm of pore-network model extraction known as the flashlight search medial axis algorithm.
