WebReaction Diffusion Equations Consider the following ODE model for population growth u t a u t u t, u 0 u0 where u t denotes the population size at time t, and a u plays the role of the … WebReaction-diffusion equations are equations or systems of equations of the form ∂ u ∂ t = ∇ ⋅ ( d ∇ u) + f ( u, t) where u is the concentration of some state variable. If the diffusion coefficient D is constant, ∇ ⋅ ( d ∇ u) = d ∇ 2 u where ∇ 2 is the Laplacian operator.
WebThese reaction–diffusion equations represent a theoretical approach to a generic chemical interaction between two species. Let us suppose that u is the activator and v is the inhibitor substance. The reaction term for the activator substance is described as a constant production ( a ), a linear consumption, and the production of the activator ...
