“…Despite this fundamental and practical importance, high quality experimental data on turbulent natural convection in enclosures including both temperature and velocity fields is quite limited [36][37][38]. The experiment of Betts and Bokhari [36] might be the only one that has easily accessible public data at http://cfd.me.umist.ac.uk/ ercoftac/ (case 79).…”

“…The standard deviation of the vertical velocity, equal to the root mean square of the velocity fluctuations, simply vertical fluctuating velocity [19], is shown in Figure 4. The figure shows that the level of the fluctuating velocity near the plume core is higher than that at the edges.…”

“…The basic set up for such flows, which has also attracted most attention from researchers, is a rectangular cavity filled with dry air whose opposing vertical walls are heated differentially [3][4][5][6]. In the case of a rectangular cavity of height H, the natural convection heat transfer from hot to cold walls is characterized by the formation of a slow moving vortex.…”

The work reported in this paper is a numerical study of airflow and heat transfer for low turbulence buoyancy-driven flow in a rectangular cavity partially filled with solid objects. The two vertical walls were maintained at constant temperatures giving a temperature differential of 42.2 °C resulting in a characteristic Rayleigh number of 1.45×109. Two different types of blockage arrangements were considered for analysis, and these consist of In-line and Staggered arrangements of 12×6 and 12×3 objects. In all cases, steady state flow and wall heat transfer data at the mid-height and mid-width of the cavity are presented. The flow domain displayed a stable core region and the average core temperature was found to be strongly influenced by different stacking arrangement of solid objects. In general, the staggered arrangement resulted in lower heat transfer through the surfaces which is linked with the suppression of turbulence within the boundary layers close to the surfaces.
