Incomplete Mixing in Reactive Systems - From Lab to Field Scale

ABSTRACT:In order for two items to react, they must physically come into contact. In the lab, reaction rates are often measured by forcing two species to continuously mix together. However, in real systems such forced mixing may not exist. A natural question arises: How do we take measurements from our well mixed laboratory experiments and use them to make meaningful predictions at scales of interest? In this talk, Bolster proposes a novel modeling framework that aims precisely to make predictions at scale. He will discuss a few examples: (i) mixing driven reactions in a quasi-well- mixed systems, (ii) mixing driven reactions in a porous column experiment, and (iii) mixing in a highly heterogeneous aquifer with a broad range of velocity and spatial scales.
