Miscible Displacement in Porous Media - I

This course covers the comprehensive understanding of flow through porous media with a special focus on miscible displacement. It starts with the introduction of Darcy's law, Ergun equation, and various transport mechanisms. The course then delves into the concept of miscible displacement, where a fluid is injected into a porous medium and mixes with the fluid already present. It further explains the effects of Poiseuille's flow and Knudsen diffusion on the effective permeability of the medium. The course also discusses the dispersion of a solute in porous media, differentiating between dispersion and diffusion. It concludes with the application of Fick's second law to understand the diffusion of a pulse in a static system. The course also covers the concept of residence time, Taylor dispersion, and the impact of a step change in concentration on the flow and dispersion process.
