Abstract
Natural convection and heat transfer of fluid flow are studied numerically inside a
rectangular cavity with inclination filled with a porous medium. The mass and
momentum equations are given by the Darcy equations coupled with the
thermal energy equation through the unsteady Boussinesq approximation. The
two-dimensional restriction in terms of the stream function and vorticity variables is
considered. The study is analyzed in terms of several values of the parameters that
determine the evolution of the flow: the Rayleigh Number, the aspect ratio of the
cavity and the angle of inclination.
