When bimolecular fronts form in solutions, their dynamics is likely to be affected
by chemically driven convection such as buoyancy- and Marangoni-driven flows. It is
known that front dynamics in the presence of buoyancy-driven convection can be predicted
solely on the basis of the one-dimensional reaction-diffusion concentration profiles
but that those predictions fail for Marangoni-driven convection. With a two-dimensional
reaction-diffusion-Marangoni convection model, we analyze here convective effects
on the time scalings of the front properties, together with the influence of reaction
reversibility and of the ratio of initial reactants' concentrations on the front dynamics.
The effect of buoyancy forces is here neglected by assuming the reactive system to
be in zero-gravity condition and/or the solution density to be spatially homogenous.This
article is part of the theme issue 'New trends in pattern formation and nonlinear
dynamics of extended systems'.
