| Résumé : | At the interface generated in the mixing of miscible fluids , instabilities can displayed by the difference between the fluids densities and diffusion coefficients. These instabilities generate characteristic patterns that affect the mass transport between the two species. BZ reaction (Belousov-Zhabotinsky) is a chemical re action where, due to the autocatalysis of its intermediaries and the difference between diffusion coefficients ofthe same, are generated chemical oscillations and waves that result in pattern formation when the reaction is carried out in two-dimensional media.The aim of this study is to analyze the influence of reaction diffusion on the instabilities caused by the contact of two fluids of different density and diffusion coefficient. The mathematical models involved in these phenomena are solved using numerical methods such as finite differences, finite volumes and finite elements. |
