%X This paper reports a transient state numerical investigation of irreversibility in a saturated porous channel, of an aspect ratio A= 5, under vertical thermal and mass gradients. The governing equations, using the Darcy-Brinkman formulation, have been solved numerically by using Control Volume Finite Element Method (CVFEM). Only two variables are taken into account, the Schmidt number and the floatability ratio. The other parameters values are fixed related to the Poiseuille¨CBenard flow (at zero mass gradients). Results reveal that the flow tends towards the steady state with different regimes, which depends on both the Schmidt number and the buoyancy ratio
