A horizontal porous layer with an impermeable adiabatic bottom wall and an impermeable isothermal top wall is studied. An impressed concentration gradient across the layer is assumed.

Abstract

A horizontal porous layer with an impermeable adiabatic bottom wall and an impermeable isothermal top wall is studied. An impressed concentration gradient across the layer is assumed. A linear stability analysis is carried out both numerically and by a first-order perturbation method. It is shown that the combined effects of viscous dissipation and mass diffusion may lead to the instability of a basic horizontal uniform flow through the layer.
