The development of spatial structure in an ionic chemical system induced by applied electric fields

摘要: The spatio-temporal structures that can arise in an ionic chemical system with a cubic autocatalytic reaction step (Gray-Scott kinetics) the presence of applied electric field are described. A linear stability analysis resulting reaction-diffusion-advection system, different diffusion coefficients and consequently electrochemical migration rates for reacting species, suggests possibility both convective ('DIFICI') Turing patterns (as well as interaction between them). detailed determines domain existence these features parameter space, predictions from which confirmed by extensive numerical simulations. These reveal wide variety propagating be sustained depending on strength whether ratio autocatalyst substrate is above or below critical values bifurcations.
