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…
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…
When Do Complex Transport Dynamics Arise in Natural Groundwater Systems?
J. Wu, D. R. Lester, M. G. Trefry +1
In a recent paper (Trefry et al., 2019) we showed that the interplay of aquifer heterogeneity and poroelasticity can produce complex transport in tidally forced aquifers, with sign…
Lagrangian transport and chaotic advection in three-dimensional laminar flows
Michel Speetjens, Guy Metcalfe, Murray Rudman
Transport and mixing of scalar quantities in fluid flows is ubiquitous in industry and Nature. Turbulent flows promote efficient transport and mixing by their inherent randomness.…
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…
Chaos and the Flow Capture Problem: Polluting is Easy, Cleaning is Hard
Lachlan D. Smith, Guy Metcalfe, Julio M. Ottino
Cleaning pollution from a heterogeneous flow environment is far from simple. We consider the flow capture problem, which has flows and sinks in a heterogeneous environment, and inv…
