Heat Transfer and Characterization in Porous Media

This course covers the comprehensive understanding of heat transfer and characterization in porous media. It begins with the introduction of heat transfer in porous media, focusing on fluid flow and temperature front traveling. The course further explains the concept of thermal equilibrium, non-equilibrium methods, and volume averaging methods. It provides a detailed explanation of temperature profiles, heat conduction, and sensible heat carried by fluid flow. The course also discusses the implications of thermal equilibrium, boundary conditions, and dimensionless parameters. It introduces the mean field model based on volume averaging approach, explaining the concept of thermal non-equilibrium and the exchange of heat between fluid and solid phases. The course concludes with the characterization of a porous medium, measurement of porosity, internal surface area, and pore volume, and various characterization methods such as optical method, imbibition method, density method, gas expansion porosimetry, and mercury porosimetry.
