Detailed Description

This class models the ion transportation in a flame.

There are three stages of the simulation.

The first stage turns off the diffusion of ions due to the fast diffusion rate of electron without internal electric forces (ambi- polar diffusion effect).

The second stage evaluates drift flux from electric field calculated from Poisson's equation, which is solved together with other equations. Poisson's equation is coupled because the total charge densities depends on the species' concentration. See Pedersen and Brown [30] for details.
