Natural convection in a square cavity with a centrally located partition is considered. While one of the side walls is fully active, the other is partly insulated. Numerical simulation, based on the finite element method, has been carried out for different lengths of the active surface. The results have been compared with the cases when the cavity is without partition as well as the case of a partitioned cavity with fully active side walls. © 1992, MCB UP Limited.

Laminar natural convection in rectangular enclosures divided by a single thin partition is studied numerically by the finite-element method. Special emphasis is given to enclosures with aspect ratios less than 1, although the results for aspect ratios of 1 have also been reported for comparison. The effect on flow structure and heat transfer of shifting the partition in the enclosure has also been investigated. While the Prandtl number is held at unity, the Rayleigh number is considered over a wide range, that is, from 103 to l06and the aspect ratio assumed the values of 1, 0.8, 0.5, and 0.4. © 1992 by Hemisphere Publishing Corporation.

Natural convection heat transfer in an enclosure with a partition - a finite-element analysis

Numerical results are reported for two cases of (1) a differentially heated comer region with a cold wall on the top as well as a comer formed by a cold vertical wall and a heated horizontal wall and (2) a cavity heated from below and partially cooled along one side. Finite element simulations indicate several interesting features of the flow structures in these two cases. © 1991 by Hemisphere Publishing Corporation.
