報(bào)告內(nèi)容簡介：

Direct numerical simulation (DNS) and microfluidics are very useful research tools for exposing the details of complex flows encountered in porous media and for averaging. This presentation will present DNS of flow and transport conducted in my group, most of which utilized the lattice Boltzmann method and random-walk particle tracking. Through these simulations, one can obtain porous media properties that are typically obtained from a conventional core analysis. When it comes to multiphase flows, however, DNS is still challenging and expensive. Microfluidics thus remains as a most practical approach. Then it will discuss will microfluidic visualizations of water and surfactant flooding as well as quantification of polymer-induced permeability damage and its correlation to distributions of fluids. Last, but not least, is the properties of fluids under phase equilibrium in reservoir that must be faithfully reproduced in any pore-scale studies. Calculations of phase equilibrium and fluid distribution should consider the effects of interfacial tension and wetting as the pores of interest becomes increasingly smaller.
