Analytical Modeling of Natural Convection in a Tall Rectangular Enclosure with Multiple Disconnected Partitions

Natural Convection in a Tilted Rectangular Enclosure with a Single Discrete Heater

The effect of inclination angle on the steady laminar free convection in a rectangular enclosure (aspect ratio = 5), which is discretely heated by an isoflux flush mounted small heater (L / H = 0.125) is studied numerically. The local and average Nusselt numbers are compared at inclination angles from 0 (bottom heating) to 180o (top heating), for modified Rayleigh numbers 102 ≤ Ra* ≤ 106. The t...

CFD analysis of natural convection heat transfer in a square cavity with partitions utilizing Al2O3 nanofluid

In the present study, natural convective heat transfer in a partitioned square cavity utilizing nanofluids is studied. The vertical left and right walls are considered as the hot and cold walls, respectively and the partitions assumed to be adiabatic. The nanofluid used in this study is Al2O3 with the volume fraction of 20%. It is assumed that nanofluid is a single phase f...

Effect of Partial Partitions on Natural Convection in Air Filled Cubical Enclosure with Hot Wavy Surface

Natural convection in cubical enclosure with hot surface geometry and partial partitions has been analyzed. The geometry is a cube with wavy hot surface (three undulations) and three partitions. The investigation has been performed for different partitions lengths and Rayleigh number while the Prandtl number kept constant. This problem is solved by using the partial differential equations which...
