Steady State AHL Gradient Approximation

In the reaction-diffusion model we have formalized the gradient establishment and we solved the resulting partial differential equation numerically. Now, the aim is to derive a suitable analytical approximation.

Kolmogorov-Petrovsky-Piskounov Equation

A reaction–diffusion equation concerning the concentration of a single molecule in one spatial dimension is known as the Kolmogorov-Petrovsky-Piskounov Equation. In our case, the equation for AHL has the following general structure:

\begin{align} \frac{\partial AHL(\textbf{r},t)}{\partial t} = Diff(AHL(\textbf{r},t),\textbf{r}) + R(AHL(\textbf{r},t)) \end{align}

And a less general form, as derived for the reaction-diffusion model for AHL:
