Mixing in Heterogeneous Media Across Spatial and Temporal Scales: From Local Non-Equilibrium to Anomalous Chemical Transport and Dynamic Uncertainty
Mixing in Heterogeneous Media Across Spatial and Temporal Scales: From Local Non-Equilibrium to Anomalous Chemical Transport and Dynamic Uncertainty
Transport, mixing and reaction of solutes and particles in natural media are of central importance in many fields of science and engineering, ranging from contaminant dispersion in geophysical flows to diffusion in living cells. Transport in these intrinsically heterogeneous media is characterized by early and late solute and particle arrivals, tailed spatial distributions, and scale effects in measured parameters. These behaviors cannot be explained by available models based on Fick’s law and are called anomalous despite their ubiquity.
