| Abstract | ||||
| Convective heat transfer through a vertically multilayered porous media is examined numerically. The examination is focused upon the effect of the temperature. Flow fields and different regimes of the heat flow. The study was done on a model with vertical isothermal walls at different temperatures and horizontally perfect insulated walls, and for three layered porous medium in which the first and third layers have equal thicknesses and permeabilities. The numerical results are reported for a range of the permeability ratio of the inner sub-layer 0.1<kr 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 | ||||
