Turing Patterns in Forced Open Two‐Side‐Fed‐Reactor

The mechanism suggested by Turing for reaction-diffusion systems is widely used to explain pattern formation in biology and many other areas. persistence of patterns altering environments an important property natural cases. experimental study these phenomena can be done chemical using appropriately designed reactors, e.g., two-side-fed open gel reactors. This configuration allows testing the effect time-periodic boundary conditions that generate periodic feeding chemicals on dynamics patterns. numerical approach based a chemically realistic 2D description reactor reproduces from boundaries corresponding concentration gradients. Depending amplitude frequency forcing, two basic regimes are observed, spatiotemporal oscillations pulsating spot pattern. In between them, mixed-mode also develop. Spot survive large forcing. pulsation analyzed detail, considering tanks gradients localize These findings suggest effectively controls systems.
