Natural Convection of a Radiating Fluid in a Partially Divided Square Enclosure

Effects of thin fin on natural convection in porous triangular enclosures

“…Many researchers studied the problem of divided rectangular or square nonporous enclosures with partition. The partition length, thickness and location centers are governing parameters for heat transfer as shown by Turkoglu and Yucel [27], Zimmerman and Acharya [28], Dagtekin and Oztop [29], Ben-Nakhi and Chamkha [30], Hasnaoui et al [31], Yucel and Ozdem [32], Dagtekin et al [33], Oosthuizen and Paul [34], Bilgen [35]. These studies are analyzed for rectangular or square shaped geometries and non-porous medium.…”

Heat Transfer Reduction due to a Ceiling-Mounted Barrier in an Enclosure with Natural Convection

“…However, a partition (or partitions) can be used as a control parameter to reduce or enhance heat transfer and flow strength inside an enclosure [5][6][7]. The enclosures can be divided by a partition hanging from the top wall or extending from the bottom floor [8][9][10][11] or both [12][13][14] or from side walls [15][16][17][18][19][20]. The thermal state of the partition plays an important role on the heat and fluid flow in a cavity.…”

“…Thermally, a partition behaves between two limiting cases. The partition may be made of highly conductive materials, and thus the partition temperature will be at the temperature of the mounted wall [9][10][12][13][14][15][16][17][18], or the thermal conductivity of partition may be very low, and thus no temperature gradient exists between the partition surfaces and adjacent fluid [7,8]. The present study is focused on the effects of the latter partition, meaning that the thermal conductivity of partition is very low compared to the fluid thermal conductivity.…”

“…Other examples of their studies can be found in references [13] and [14]. In the context of location of partitions onto two walls, studies were performed and reported in references [15] and [16]. In the studied cases, a jet-like flow is formed between partitions due to the narrow region, and strength of flow is decreased.…”

A Differential Quadrature Solution of Natural Convection in an Enclosure with a Partial Partition

“…Fluid flow and heat transfer in an enclosure with a sinusoidal upper wall temperature has been examined by Sarris et al [21]. The influence of radiation has been taken into consideration in a part of the studies on natural convection in simple enclosures [22][23][24][25].…”
