An iterative procedure to obtain the concentration dependency of the diffusion coefficient from the space-averaged concentration vs time
A numerical method is presented to obtain the dependency of the diffusion coefficient on the concentration when the space-averaged concentration is known as a function of time. The method uses a correction of computed concentration profiles and a successive substitution of a diffusion coefficient dependency to approach the true dependency.
