Nonlinear reactions advected by a flow

Flows can modify the effects of nonlinear reactions. Here we use a lattice Boltzmann method to simulate an athermal flow which advects reactant species. As an example we consider a reactive system modeled by the Brusselator which exhibits Turing structures; the system is subjected to mixing as induced by the wakes behind obstacles. The resulting effect is a modification of the reaction patterns which can be as dramatic as their disappearance.
