Abstract

In the present work forced convection flow in a channel partly filled with a porous media under asymmetric heat flux, boundary condition has been investigated. The porous material is distributed on the bottom wall of the channel. Darcy– Brinkman and LTNE model have been assumed in order to solve momentum and energy equations, respectively. Fully developed conditions are considered in order to solve velocity and the temperature fields. Due to the different configuration of porous media, new velocity profiles are introduced. The Nusselt number (Nu) is deduced in terms of the porous thickness(S), thermal conductivity ratio (k) and Darcy number (Da). The results illustrate that the fluid temperature in the clear region declines when the porous thickness grows at constant k. The temperature difference between the fluid phase and the solid phase decreases, as Bi increases. There are two stages for variation of Nu number with S and the optimum Nusselt thicknesses of the porous medium Sopt, Nu is found for different value of k and Bi. Moreover, at the particular value of S Nu number is independent of Bi and k for each Da number.
