Natural Convection in an Inclined Enclosure With an Off-Center Complete Partition

Theoretical investigation of natural convection heat transfer in inclined and fully divided CO2 enclosures on Mars

“…Additionally, the aspect ratios in the cases of Ar = 2, 1.5, 0.25~4, 1~2, 1, 2, 4, and 1 in Ref. [20][21][22][23][24][25][26][27], respectively, were not high as Ar = 7.14 as examined in the present study. The enclosure depth (the length in the perpendicular direction of the xy plane) was sufficiently large (1000 mm) in comparison to the enclosure thickness (140 mm), so the effect of the adiabatic boundary condition in the perpendicular direction of the xy plane was negligible and a two-dimensional model was assumed, and this was also confirmed in previous studies [2,29].…”

“…They indicated that the temperature of partition increased monotonically along its length, and the influence of Rayleigh number on the partition temperature was limited when the tilt angle was 45°. Tsang and Acharya [26] performed a numerical study on the natural convection in an inclined air rectangular enclosure with an off-center complete partition at tilt angles of 30°, 45°, 60°, and 90°. They pointed out that the effect of partition location on the partition temperature distribution decreased with increasing Rayleigh number.…”

“…However, in the present study, the influence of partition number and tilt angle on the heat transfer in fully divided CO2 enclosures on Mars surface was studied. Given the Earth surface condition, a few studies [20][21][22][23][24][25][26][27] focused on familiar issues.…”

Natural convection in a partitioned enclosure heated from below

“…In previous studies [3, 41, a theoretical and experimental investigation have been performed for the heat transfer phenomenon through centrally located vertical partitions surrounded by thermally stratified fluid. In references [5,6], numerical results have been obtained for various location of the impermeable partition at different Rayleigh number. The primary interest of references [3 -6] is the effect of the partition on the natural convective heat transfer.…”
