The dual-mesh hybrid numerical method is used to investigate the salt finger convection, as well as the heat and mass transfer, in saturated porous media. It is found that at low normalized porosity of porous media, saline diffusion is much faster than thermal diffusion. The fingers grow straightly to the top and bottom walls, which would lessen the saline gradient of stratified system. Also, it is indicated that the hybrid method is perfect for dealing with small scale convection in porous media because of its great veracity, efficiency and stability.
