| Abstract | ||
| In this paper a numerical study for the natural convection in an enclosure with adjacent single wall using vertical adiabatic partition attached to bottom wall. The vertical walls of the enclosure are isothermal while the bottom and top horizontal walls are insulated. The temperature of the left vertical wall is higher than the temperature of the right vertical wall. The study included a change in the inclination of the cold wall of (f=15°, 30° and 45°), Rayleigh number of (Ra=103 to 105), length of partition of (YP= 0.2, 0.3 and 0.4) and location of partition of (XP=0.25 and 0.5). A finite difference method was applied to solve the governing equations using Gauss-siedel iterative technique. Results for the mean Nusselt number, and contour maps of the streamlines and isotherms line are presented. It has been found that Nusselt number increases with an increase in Rayleigh number, inclination of cold wall with percentage of (10-16%) and location of partition with percentage of (3-14%) while decreases with increasing in partition length with percentage of (5.4-7%). | ||
