Cyprien Soulaine - Simulation Techniques to model flow and transport at the pore-scale

This presentation was presented during the 4th Cargèse Summer School on Flow and Transport in Porous and Fractured Media in 2018. Don’t hesitate to have a look on other lectures of the summer school on our channel! More information on the Summer School on https://cargese2018.sciencesconf.org/ ** Recent interests in CO2 sequestration or in unconventional oilrecovery rose new challenges for porous media research as the systems to be modeled evolve in time and may exhibit strong coupling between mass and heat transfer, and eventually rock mechanics. To characterize or to get new insights on large scalephysics, a general strategy consists in going to the pore-scale where the physics is well established and then upscale the results. At that scale, the geometry of the complex pore space enclosed by the solid skeleton is described in complete detail, boundary conditions at the fluid/solid interface are specified and the equations of fluid mechanics are solved, namely Navier-Stokes equations. With the recent improvements in imaging techniques such as X-ray computed microtomography combined with modern High Performance Computing techniques it is now possible to have access to the exact three dimensional (3D) structure of a rock sample and to solve the flow in the void space. In this lecture, we review different Navier-Stokes-based simulation techniques to model fluid flow and transport in porous media at the pore-scale.
