Miscible Displacement in Porous Media - II

This course covers the comprehensive understanding of flow through porous media, focusing on miscible displacement and the dispersion of solute or tracer in the porous media. For instance, it explains how a step change in concentration at the inlet affects the mixing and outlet concentration when the flow is constant. The course introduces the governing equation for a static system and how it changes for a flow process. It further discusses the concept of Taylor dispersion, the role of the dispersion coefficient, and the impact of velocity profiles on the dispersion process. The course concludes with an explanation of how to interpret concentration profiles to understand the quality of a porous medium. It also explores the concept of Peclet number, Dirac function, and its importance in understanding the different regimes of flow. The course delves into the characterization of porous media based on the mixing process, the effect of stagnant zones and fractures on the flow and mixing in porous media. It also discusses the governing equation for reactive flow in porous media, taking into account accumulation, diffusion, convection, and reaction.
