Oral Presentation (MS08) Mixing, dispersion and reaction processes across scales in heterogeneous and fractured media MS08

Speaker

Timothy Ginn (Washington State University)

Description

Understanding the way that mixing during transport in porous media governs the kinetic rate of bi-molecular reactions has grown through original experiments and new theories. A long-awaited expansion in the set of controlled experiments now inspires broader testing of proposed theories. Here we apply our ballisticule-based quasi-closed form solution to mixing-limited reactive transport experiments including pre-asymptotic dispersion, to the updated cohort of experiments. We present results of this broader testing including exploration of the dependence of mixing rate parameter values on physico-chemical properties through reliance on the Buckingham π theorem.
