A numerical study was performed to further investigate the flow and temperature fields in layered porous cavity. The cavities considered have an aspect ratio of either 0.2 (shallow cavities) or 5 (tall cavities) with two or four sublayers. Similar to the case of square cavities, convection is always initiated in the more permeable sublayer. As the base Rayleigh number increases, the strength of the convective cell increases and leads to flow penetration to the less permeable sublayer
