The role of a delay time on the spatial structure of chaotically advected reactive scalars
Alexandra Tzella, Peter H. Haynes
The stationary-state spatial structure of reacting scalar fields, chaotically advected by a two-dimensional large-scale flow, is examined for the case for which the reaction equati…
Diffusion of passive scalar in a finite-scale random flow
A. A. Schekochihin, P. H. Haynes, S. C. Cowley
We consider a solvable model of the decay of scalar variance in a single-scale random velocity field. We show that if there is a separation between the flow scale k_flow^{-1} and t…
Chaotic mixing induced transitions in reaction-diffusion systems
Zoltan Neufeld, Peter H. Haynes, Tamas Tel
We study the evolution of a localized perturbation in a chemical system with multiple homogeneous steady states, in the presence of stirring by a fluid flow. Two distinct regimes a…
The effect of forcing on the spatial structure and spectra of chaotically advected passive scalars
Zoltan Neufeld, Peter H. Haynes, Guillemette Picard
The stationary distribution of passive tracers chaotically advected by a two-dimensional large-scale flow is investigated. The tracer field is force by resetting the value of the t…
Chaotic advection of reacting substances: Plankton dynamics on a meandering jet
Cristobal Lopez, Zoltan Neufeld, Emilio Hernandez-Garcia +1
We study the spatial patterns formed by interacting populations or reacting chemicals under the influence of chaotic flows. In particular, we have considered a three-component mode…
Smooth-filamental transition of active tracer fields stirred by chaotic advection
Zoltan Neufeld, Cristobal Lopez, Peter H. Haynes
The spatial distribution of interacting chemical fields is investigated in the non-diffusive limit. The evolution of fluid parcels is described by independent dynamical systems dri…
