Mixed Convection Heat Transfer Enhancement in a Vented Cavity Filled with a Nanofluid

Influence of active flow modulation on conjugate mixed convection inside a vented cavity

“…A recent comprehensive review of mixed convection in different shapes of enclosure by Izadi et al 1 revealed that very few researches had been done by considering vented cavity over other closed type square/rectangular cavities. However, nowadays, mixed convection inside vented cavity has attracted many researchers [2][3][4][5][6] due to its frequent encounter in the above-mentioned applications. For example, Saha et al 2 analyzed the mixed convection phenomena in a rectangular vented cavity for various configurations of the inlet and the outlet openings, and concluded that for ensuring cooling effectiveness, the exit port must be positioned at the top of the right wall whereas the inlet could be positioned either at the bottom or at the top of the left boundary.…”

“…They suggested that natural convection dominated the heat transfer process at relatively lower Reynolds number, while the forced convection effect became more prominent at relatively higher Reynolds number. Bahlaoui et al 4 carried out research on mixed convection heat transfer using water-Al 2 O 3 nanofluid in a vertically vented rectangular cavity heated from one side with a view to studying the improvement of heat transfer by imposing either suction at the outlet or injection at the inlet. They found that suction at the outlet resulted in more efficient heat transfer than injection at the inlet.…”

Viscous dissipation effect on mixed convective heat transfer of MHD flow of Williamson nanofluid over a stretching cylinder in the presence of variable thermal conductivity and chemical reaction

“…Accordingly, some researchers have examined mixed convection flows. Among these, Bahlaoui et al 25 studied nanofluid flows in a vertical vented rectangular enclosure with mixed convective heat transfer. Entropy generation effectiveness in hydromagnetic mixed convection heat transfer over a rotating disc in the presence of partial slip effect was scrutinized by Ijaz Khan et al 26 Moreover, Billah et al 27 inspected mixed convection flow through a rectangular channel.…”

Mixed Convection and Entropy Generation of an Ag-Water Nanofluid in an Inclined L-Shaped Channel

“…A nanofluid is the dispersal of solid nanoparticles with superior thermal conductivity into the working base fluid [17]. A nanofluid is a familiar strategy in enclosures [18], nevertheless, they are used in vented cavities [8,[19][20][21][22] and channels [23][24][25]. In practice, these vented cavities and channels are parts of an enclosed loop system because the nanofluid is toxic and expensive.…”
