Modeling of a microbial growth experiment with bioclogging in a two-dimensional saturated porous media flow field.

Interaction between water flow and spatial distribution of microbial growth in a two-dimensional flow field in saturated porous media.

Bacterial growth and its interaction with water flow was investigated in a two-dimensional flow field in a saturated porous medium. A flow cell (56 x 44 x 1 cm) was filled with glass beads and operated under a continuous flow of a mineral medium containing nitrate as electron acceptor. A glucose solution was injected through an injection port, simulating a point source contamination. Visible li...

Bioclogging in porous media: Model development and sensitivity to initial conditions

15 This work presents a numerical model able to simulate the effect of biomass growth on the hydrau-16 lic properties of saturated porous media, i.e., bioclogging. A new module for an existing coupled 17 flow and reactive-transport code-PHWAT-was implemented. Laboratory experiments were used to 18 validate the model.. Good agreement with the experimental data was found. Model behavior was 19 sa...

Application of the Boundary Element Method to two Dimensional Dynamic Problems of Saturated Porous Media

Axi-Symmetric Deformation Due to Various Sources in Saturated Porous Media with Incompressible Fluid

The general solution of equations of saturated porous media with incompressible fluid for two dimensional axi-symmetric problem is obtained in the transformed domain. The Laplace and Hankel transforms have been used to investigate the problem. As an application of the approach concentrated source and source over circular region have been taken to show the utility of the approach. The transforme...

Investigation of pore-scale random porous media using lattice boltzmann method

The permeability and tortuosity of pore-scale two and three-dimensional random porous media were calculated using the Lattice Boltzmann method (LBM). Effects of geometrical parameters of medium on permeability and tortuosity were investigated as well. Two major models of random porous media were reconstructed by computerized tomography method: Randomly distributed rectangular obstacles in a uni...
