Contribution à l'étude de la diffusion de la matière dans un canal.

Abstract

In this work, we recall the theoretical bases of the phenomenon of diffusion of material into a channel. Then, the numerical study a phenomenon and laminar flow. Our study regroup two parts: The first is to give a general description of the phenomenon. The second is the phenomenon study using a mathematical model called MATHEMATICA that delivers results to equations of partial derivatives graphically in 2 to 3 dimensions. The algorithm is used to obtain the field of concentration starting from the equation of continuity. The code of calculating was validated based on the results which were available in the literature.
