Brusselator simulation in 1-D space. Left column: dispersion curve of real (α) and imaginary (ω) parts of dominnat eigenvalues predicting the emergent pattens for two sets of parameters: (a) A = 2.5, B = 9, D _X  = 7, D _Y  = 10; (b) A = 2, B = 4.8, D _X  = 2, D _Y  = 10. H: Hopf mode with α > 0,ω > 0 at wavenumber q = 0; T: Turing mode with α > 0,ω = 0 at q ≠ 0; DT: damped Turing with α < 0 at q ≠ 0; DH: damped Hopf with α < 0 at q = 0. Right column: one-dimensional Brusselator model of length 60 cm with periodic boundary condition evolves in time running rightwards during 30 s. Colour indicates the local concentration of the reactant: [red] high concentration, [blue] low concentration.
