Abstract

The emergence, growth and stabilization of stationary concentration patterns in a continuously fed chemical reation-diffusion system are studied through numerical simulation of the Lengyel-Epstein model. Using the supply of iodine as a control paramter, the regularity of the hexagonal patterns that develop from the noise infected homogeneous steady state is examined. In the region where they are both stable, the competition between Hopf oscillations and Turing stripes is studied by following the propagation of a front connecting the two modes. Examples are presented of the types of structures that can develop in the presence of a feed gradient.
