Abstract

The evolution of a competitive-consecutive chemical reaction is

computed numerically in a two-dimensional chaotic fluid flow with

initially segregated reactants. Results from numerical simulations are

used to evaluate a variety of reduced models commonly adopted to model

the full advection-reaction-diffusion problem. Particular emphasis is

placed upon fast reactions, where the yield varies most significantly

with Peclet number (the ratio of diffusive to advective time scales).

When effects of the fluid mechanical mixing are strongest, we find that

the yield of the reaction is underestimated by a one-dimensional

lamellar model that ignores the effects of fluid mixing, but

overestimated by two other lamellar models that include fluid mixing.
