Porous media

From Thermal-FluidsPedia

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.
