Fast Binary Reactions and the Lamellar Approach

As a first case study to consider the impact of advection processes on reaction-diffusion dynamics (thus leading to the full reaction-diffusion-advection problem) we address here the case of a binary reaction. The limit of a fast reaction (as compared with diffusion) becomes simple to analyze, and the filament or lamellar approach developed in Sect. 2.7.1 is a very appropriate tool to understand the dynamics in simple geometries and to interpret observations in more complex ones.
