A kinetic description is proposed of a fluid species moving in a porous medium and chemically interacting with it. The porosity is included in the model by a modification of the standard kinetic equations for two gaseous species diffusing in a background medium of two solid species. The validity of the proposed kinetic model is assessed by comparing the resulting macroscopic model, obtained by Chapman–Enskog expansion, with macroscopic models present in the literature.

Abstract
A kinetic description is proposed of a fluid species moving in a porous medium and chemically interacting with it. The porosity is included in the model by a modification of the standard kinetic equations for two gaseous species diffusing in a background medium of two solid species. The validity of the proposed kinetic model is assessed by comparing the resulting macroscopic model, obtained by Chapman–Enskog expansion, with macroscopic models present in the literature.File in questo prodotto:
