Transport in porous media is applicable to a wide range of fields, including mechanical, chemical, environmental, and petroleum engineering, as well as geology. Porous media can be found naturally in rocks and sand beds, and also can be fabricated as in wicks and catalytic pellets. They are an essential component in high-technology devices such as fuel cells and heat pipes.

• Basics
• Governing Equations

Contunuity, momentum, energy equations, entropy equation, and species equation.

• Multiphase Transport

Multi-fluid model (MFM) and multiphase mixture model (MMM).

• Melting and Solidification in Porous Media

Convection-controlled melting problem, and an enthalpy model for melting and solidification.

• Condensation

Inclined wall, and effect of surface tension.

• Evaporation

Wedge or cone in porous medium, and inverted meniscus in porous media.

• Boiling

Nucleate boiling in a wicked surface, boiling in porous media heated from below and film boiling.
