Abstract

Experimental study was carried out for the steady laminar natural convection of air in an inclined annulus porous medium, with constant heat flux heated inner cylinder and an isothermally cooled outer cylinder. The primary objective of the study is to show the effect of the inclination angle of the annulus on the local and maximum temperatures of the heated inner cylinder and the local and mean Nusselt number. The geometrical parameters of the annulus are; diameters of 21/45mm, gab width=12mm, length of 492 mm, and an aspect ratio (length-gab width) =41. The annulus is filled with spherical beads of diameter d=6.3 mm with porosity of 0.45. The operating parameters are: heat results show great influence of the inclination angle on the local and maximum surface temperature as well as the local and mean Nusselt number. The average Nusselt number is correlated with both the inclination angle 0 and the Raylrigh number.
