Porous Media

Flow in porous media

Transport and flow phenomena in porous media occur in various fields of science and engineering, ranging from agricultural, biomedical, chemical and petroleum engineering to soil sciences. Despite the huge interest on this topic, relations between flow and transport properties of porous media and the corresponding microstructure are not fully understood.

We analyze flow and transport properties of microfluidic porous PDMS structures, with full knowledge of the microstructure and real space visualization of fluid flow and particle transport.
