In the talk, a Darcy scale model capable of simulating microbialtransport and accumulation in saturated porous media is presented. Themodelled processes include biomass growth and decay, transfer processesbetween the bulk fluid and the solid and advective/dipsersive transportof bacteria with the bulk fluid.
The model is intended to be used in simulations of microbial clogging inan underground CO2 storage site and thus two fluid phases need to beaccounted for. The extension from one-phase to two-phase flow is notstraight-forward. The second part of the presentation focuses on theissues that need to be included in a two-phase model such as theestimation of surface areas, capillary pressure and relative permeabilities.
