| Abstract | ||||
| This paper outlined numerically a solution for the phenomenon of heal Now by natural convection in a two dimensional multilayered vertical porous medium heated from one side with vertical isothermal walls and insulated horizontal walls. The study is concentrated on the effect of changing both the permeability ratio Kr and width ratio Wr of an inner sublayer in a three layered porous medium on the different regimes of the heat flow. Numerical results are reported for the range of O<W, <1, 0.K<K Nu = C.(± 0.3836 Wr+1).(0.0454 Kr + 0.9546) Ra0.5) where the +ve is for the case of Kr>1, the --ve is for the case of Kr | ||||
