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…

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…
