Abstract

A system modeling fluid motions in horizontal porous layers, uniformly heated and salted from below, is analyzed in the case of variable thermal and solutal diffusivities. The boundedness and uniqueness of solutions are shown. A class of non-constant throughflows is found and their stability is analyzed via a new approach. Conditions of global nonlinear stability, in closed form, are obtained.
