The enormous growth in computational capabilities of recent years has made Navier–Stokes-based simulation of flow and transport in natural porous media possible. Because of the complex multiscale nature of porous media, however, full Navier–Stokes representation of the physics everywhere in the domain is not always feasible. Here, we employ, a filtering—or micro-continuum—approach to model the sma...... hiện toàn bộ
