Recent advances in high performance computing and imaging techniques have fostered pore-scale simulations of flow through porous media. We report on our experience in modeling multiphase flow with classic Computational Fluid Dynamics tools that couple the solution of the Navier-Stokes equations with the Volume of Fluid method to track the interface. First, we validate the method by modeling microfluidic experiments in Hele-Shaw cells filled with obstacles, which have been built by soft lithography. Then, we illustrate how numerical simulations can be used to demystify the meaning of macroscopic quantities (e.g., capillary pressure) and to assess the importance of mechanisms, such as inertial effects during spontaneous meniscus reconfigurations. We discuss implication and opportunity to use these tool to improve reservoir-scale predictions.
