ABSTRACT

In this contribution, we focus on a fundamental analysis of flow regimes possibly found at the microscopic scale in electrokinetic soil remediation. To accomplish this objective, a capillary bundle with three different geometries (i.e., rectangular, cylindrical, and annular) has been used to describe the microscopic-level structure of the soil domain. The analysis considers the simultaneous effects of different transport driving forces responsible for the motion of the bulk fluid and solute species, i.e., electro-osmosis, electromigration, buoyancy, and advection. The presence of these collaborative and competing forces, usually ignored or not taken into account completely, promotes distinct flow regimes that may explain important field test results. Several numerical examples are used to illustrate the flow situations found in the system for a selection of values of the parameter space. From the analysis and comparison of these graphic representations, a qualitative and semiquantitative description of the different flow regimes inside the capillary channel is obtained. In particular, the role of the capillary geometry on flow reversal is analyzed in detail, and its implications for mixing as a possible cause of lowering efficiency in soil cleaning by electrokinetic-based methods are highlighted.
