Scalar signatures of chaotic mixing in porous media
Heyman J., Lester D., Le Borgne T
Steady laminar flows through porous media spontaneously generate Lagrangian chaos at pore scale, with qualitative implications for a range of transport, reactive and biological pro…
Lagrangian complexity persists with multimodal flow forcing in poroelastic systems
Michael Trefry, Daniel Lester, Guy Metcalfe +1
We extend previous analyses of the origins of complex transport dynamics in poroelastic media to the case where the input transient signal at a boundary is generated by a multimoda…
Hierarchical Jamming in Frictional Particle Assemblies
Ruru Li, Daniel Lester
The postulate of the existence of a jamming phase diagram (Liu and Nagel, Nature 396, 21 EP (1998aa)) provides a theoretical basis for the classification of a wide range of amorpho…
Global Organization of Three-Dimensional, Volume-Preserving Flows: Constraints, Degenerate Points, and Lagrangian Structure
Bharath Ravu, Guy Metcalfe, Murray Rudman +2
Global organization of 3-dimensional (3D) Lagrangian chaotic transport is difficult to infer without extensive computation. For 3D time-periodic flows with one invariant we show ho…
Natural Groundwater Systems Can Display Chaotic Mixing at the Darcy Scale
Michael Trefry, Daniel Lester, Guy Metcalfe +1
Although steady, isotropic Darcy flows are inherently laminar and non-mixing, it is well understood that transient forcing via engineered pumping schemes can induce rapid, chaotic…
