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…
