A numerical study was performed to analyze the steady natural convection heat transfer in a two-dimensional partially filled rectangular cavity with a uniform heat-generating saturated porous medium. The boundary conditions were: two isothermal walls at different temperatures and two horizontal adiabatic walls. The study covered the range of 10{sup 3} {lt} Ra {lt} 10{sup 7} and 10{sup {minus}3} {lt} Da {lt} 10{sup {minus}8}. The aspect ratio A was varied from 0.5 to 20, the filling factor F from 0.0 to 1.0, the dimensionless porous layer location X{sup p} from 0.1 to 0.5 (symmetry line), and the asymmetric cooling {theta}{sub h} from 0.0 to 0.5. It was found that the flow and temperature fields interact in different ways depending on various parameters (Ra, Da, A, X{sub p}, {theta}{sub h}, and F).
