| Résumé : |
A previous mathematical study has shown that two kinds of two-dimensional convective patterns solve the Darcy law and the heat equation in an infinite horizontal porous layer, heated from below, where a non zero through-flow is imposed. They are travelling waves and front-like modulated rolls, with wavelengths in an interval. A numerical study which is the topic of this paper allows to describe the corresponding flows above the convective threshold. |
