A Unified Theory for Chaotic Mixing in Porous Media: from Pore Networks to Granular Systems
Daniel Lester, Joris Heyman, Yves Meheust +1
Recent studies have revealed the central role of chaotic stretching and folding at the pore scale in controlling mixing within porous media, whether the solid phase is discrete (as…
Is Chaotic Advection Inherent to Heterogeneous Darcy Flow?
Daniel R. Lester, Michael G. Trefry, Guy Metcalfe +1
At all scales, porous materials stir interstitial fluids as they are advected, leading to complex distributions of matter and energy. Of particular interest is whether porous media…
Linking Dispersion and Stirring in Randomly Braiding Flows
Daniel R. Lester, Michael G. Trefry, Guy Metcalfe
Many random flows, including 2D unsteady and stagnation-free 3D steady flows, exhibit non-trivial braiding of pathlines as they evolve in time or space. We show that these random f…
