Abstract
This paper discusses the natural convection heat transfer in an inclined triangular enclosure filled with Cu-water nanofluid saturated porous medium in the presence of heat generation effect. Two symmetric heat sources are located at the bottom and left walls of the enclosure while the remaining parts are thermally insulated. The inclined wall of the enclosure is considered to be cold. The partial differential equations governing the problem are transformed to a dimensionless form and solved numerically using an implicit finite difference method. The obtained results are presented in terms of streamlines, isotherms, local Nusselt number and average Nusselt number. It is found that a good enhancement in the average Nusselt number can be obtained by an increase in the nanoparticle volume fraction. Also, an increase in the heat generation parameter leads to a decrease in the average Nusselt number.
