This paper describes the heat transfer and fluid flow through a confined porous layer heated and cooled along one of the vertical side walls. Numerical experiments and scale analysis show that the natural circulation in this first configuration is either one of incomplete vertical penetration, or one of incomplete horizontal penetration. Scale analysis shows that the heat transfer and fluid flow scales differ substantially from one type of penetrative convection to the other, in agreement with the trends revealed by numerical simulations. When the heated portion of the side wall is located below the cooled portion, the flow spreads throughout the porous medium.
