Instabilities in propagating reaction-diffusion fronts of the iodate-arsenous acid reaction

Instabilities in propagating fronts of the iodate-arsenous acid reaction are predicted by an empirical rate-law model. The planar front loses stability when the ratio of the reactant diffusivity to the autocatalyst diffusivity exceeds a critical value. The relative diffusivities can be altered by introducing a reagent that reacts specifically with the autocatalyst to form an immobile complex. E...

Fingering instabilities in propagating fronts of the CO oxidation reaction on Pt(100)

Introduction Interfacial patterning is a common feature of many non-linear systems ranging from isothermal chemical reactions [1] to viscous flow systems [2]. Underlying this behavior is the spatial decoupling of chemical species due to differences in convective or diffusive transport. The oxidation of CO on Pt(100) represents a non-linear system where adsorbed CO and O are significantly decoup...

Field theory of propagating reaction-diffusion fronts.

The problem of velocity selection of reaction-diffusion fronts has been widely investigated. While the mean-field limit results are well known theoretically, there is a lack of analytic progress in those cases in which fluctuations are to be taken into account. Here, we construct an analytic theory connecting the first principles of the reaction-diffusion process to an effective equation of mot...

Interaction between buoyancy and diffusion-driven instabilities of propagating autocatalytic reaction fronts. II. Nonlinear simulations.

The nonlinear dynamics resulting from the interplay between diffusive and buoyancy-driven Rayleigh-Taylor (RT) instabilities of autocatalytic traveling fronts are analyzed numerically for fronts ascending or descending in the gravity field and for various values of the relevant parameters, the Rayleigh numbers R(a) and R(b) of the reactant A and autocatalytic product B, respectively, and the ra...

Biscale chaos in propagating fronts.

The propagating chemical fronts found in cubic autocatalytic reactiondiffusion processes are studied. Simulations of the reaction-diffusion equation near to and far from the onset of the front instability are performed and the structure and dynamics of chemical fronts are studied. Qualitatively different front dynamics are observed in these two regimes. Close to onset the front dynamics can be ...
