The chemical reactions take place on the walls of the porous médium. The effective behavior of these reactive flows is described by a new elliptic boundary-value problem contalning an extra zero-order term which captures the effect of the chemical reactions.engbook parthttp://www.ams.org/bookstore-getitem/item=theta-6http://www.ams.org/restricted access517.9Ecuaciones diferenciales1202.07 Ecuaciones en Diferencias
