摘要：We give a review about the problem of thermal convection in fluids, homogeneous porous media and in tilted fractures embedded in porous media with very low permeability. In the later case we show some new results refered to the complex form of the isoterms in the porous media, nearby the fracture, and the existence of convective motion for all Rayleigh number.
