Stirring Speeds Up Chemical Reaction

Digital Publication (Archive)

We consider absorbing chemical reactions in a fluid current modeled by the coupled advection-reaction-diffusion equations. In these systems, the interplay between chemical diffusion and fluid transportation causes the enhanced dissipation phenomenon. We show that the enhanced dissipation time scale, together with the reaction coupling strength, determines the characteristic time scale of the reaction.
