Reaktiodiffuus
Reaktiodiffuus is a class of systems in which chemical reactions are coupled to the diffusion of reacting species, leading to spatiotemporal patterns. These systems are commonly described by partial differential equations that track the concentrations of two or more chemical species in space and time.
A typical two-species formulation uses concentrations u(x,t) and v(x,t) with equations of the form ∂u/∂t = D_u
Patterns observed in reaktiodiffuus systems include spots, stripes, and labyrinthine structures. Their appearance depends on kinetic
Historically, the concept was introduced by Alan Turing in 1952 as a potential mechanism for biological morphogenesis.
