We investigate the influence of multiscale aggregation and deposition on thecolloidal dynamics in a saturated porous medium. At the pore scale, theaggregation of colloids is modeled by the Smoluchowski equation. Essentially,the colloidal mass is distributed between different size clusters. We treatthese clusters as different species involved in a diffusion-advection-reactionmechanism. This modeling procedure allows for different material properties tobe varied between the different species, specifically the rates of diffusion,aggregation, deposition as well as the advection velocities. We apply theperiodic homogenization procedure to give insight into the effectivecoefficients of the upscaled model equations. Benefiting from direct access tomicrostructural information, we capture by means of 2D numerical simulationsthe effect of aggregation on the deposition rates recovering this way both theblocking and ripening regimes reported in the literature.
