SUMMARY:Solute Mixing and Mixing-Controlled Reactions in Heterogeneous Porous Media
DESCRIPTION:Natural attenuation of contaminants or any other reactive transformation in groundwater require that the reacting compounds mix at the pore scale. Particularly if mixing in the direction transverse to flow is required, the physical mixing process may be rate limiting for overall reactive turnover. This is the case for continuously emitted contaminants that require a dissolved reaction partner for degradation to occur. The presentation addresses the following questions:1) What are efficient ways of computing mixing-controlled reactive transport?2) What are practical consequences of control by mixing? Here the emphasis on the length of plumes and the overall degree of degradation.3) How does heterogeneity enhance transverse mixing and contribute to uncertainty in mixing and overall degradation?These questions are tackled by analytical methods, numerical simulation, and stochastic analysis.
