Transport in Fluid Flow

Porous Media

Local correlations of flow across pore junction predict overall flow distribution and transport. Thereby they map a local porous media architecture to global transport properties.


Uptake kinetics, molecular diffusion and flow based advection compete to control supply via molecule uptake from fluid streaming through veins.
