Abstract
Many practical problems in engineering occur over time and length scales that differ by many orders of magnitude. This makes the application of direct numerical approaches for the prediction of their response impractical. One such class of systems involves heterogeneous porous media in which small spherical porous particles are dispersed within a larger porous domain. We are interested in investigating such systems in which diffusional and convective transport in the continuous phase are coupled with diffusion and reaction/immobilization within the micro-scale inclusions; we develop multi-scale models which enable the prediction of the transient response of such systems taking into account, in a rigorous manner, the transport and reaction at the micro-scale. Immobilized bioreactors [1], ground-water or hydrocarbon flow in fractured rock [2] and ion diffusion in Li-ion batteries [3] are all potential systems of interest.
