Abstract

Different reaction-diffusion macroscopic models of propagation of a polymer in a fluid in a chromatographic column are described along with numerical schemes. The link between the apparent diffusion and the microscopic-intrinsic diffusion of the fluid and the grains is recalled using the homogenization techniques for local equations. These intrinsic properties are sought after by parameter identification of the equation governing the global behavior. Numerical simulations are performed on experimental data, assuming periodic local geometry.
