Abstract: | The lateral stability of reaction fronts in simple autocatalytic models with the components carrying various charges is investigated
when the system is exposed to an inhomogeneous electric field parallel to the direction of propagation. The enhanced migrational
flux of the reactant destabilizes the planar front giving rise to a cellular structure because the electric field strength
is greater on the reactant side of the reaction front. The onset of instability depends not only on the charge difference
between the reactant and the autocatalyst but also on the variation of specific conductance in the course of the reaction,
which results in a difference in electric field strength on the opposite sides of the reaction front. |
