Introduction to Flow Through Porous Media

Understanding how fluids move through porous structures is essential for modern engineering, from groundwater hydrology and environmental remediation to energy extraction and filtration systems. This text-only course provides a clear, step-by-step introduction to the physical principles and mathematical models that describe fluid behavior in complex media. You will start with foundational concepts like porosity, permeability, and fluid-solid interactions before advancing to practical transport equations. By reading through this comprehensive material, you will develop the analytical skills needed to solve real-world transport problems and evaluate fluid flow in various geological and synthetic materials. You will learn to apply theoretical models to practical scenarios without needing complex software. What you'll learn: - Understand the key physical properties of porous media, including porosity, tortuosity, and specific surface area. - Apply Darcy's Law to calculate fluid velocity and pressure drops in single-phase flow systems. - Formulate mass conservation and governing differential equations for multidimensional transport. - Analyze multi-phase flow behavior, relative permeability, and capillary pressure concepts. - Evaluate modern environmental and industrial applications, including aquifer management and contaminant migration. - Practice solving transport equations through structured written exercises and step-by-step analytical derivations. This course begins with core definitions and basic fluid mechanics principles, gradually building toward complex multi-phase systems and practical engineering applications. Each section is designed to reinforce your theoretical understanding through detailed written explanations and worked examples. This course is designed for engineering students, geologists, environmental scientists, and beginners looking for a solid theoretical foundation in porous media transport. No prior knowledge of porous media theory is required, though a basic understanding of introductory calculus and fluid mechanics is helpful.
