Abstract:Heat sources, such as power electronics for offshore power, could be cooled passively-mainly by conduction and natural convection. The obvious advantage of this strategy is its high reliability. However, it must be implemented in an efficient manner (i.e., the area needs to be kept low to limit the construction costs). In this study, the placement of multiple heat sources mounted on a vertical plate was studied experimentally for optimization purposes. We chose a regular distribution, as this is likely to be the preferred choice in the construction process. We found that optimal spacing can be determined for a targeted source density by tuning the vertical and horizontal spacing between the heat sources. The optimal aspect ratio was estimated to be around two.

“…Natural convection in enclosures, whose flow is caused by temperature-induced density variations, is important in many engineering applications, such as heat exchanger, nuclear and chemical reactors, cooling of electronic equipment and solidification processes [1]. Natural convection problems are studied mostly for square or rectangular geometries at different thermal and solute boundary conditions as given in literature [2,3].…”

“…Among the non-rectangular enclosure, a parallelogrammic enclosure is an important type of enclosure and aptly describes the physical configuration of many applications. A detailed investigation of free convection in a parallelogrammic enclosure for engineering applications with special attention to the case of parallelogrammic diode cavity can be found in Bairi et al [1]. Baytas and Pop [2] studied convective flow and heat transport in oblique enclosures filled with porous medium.…”

Abstract.A numerical study is conducted to understand the effect of magnetic field on the natural convection in a tilted parallelogrammic porous enclosure. The two opposing side walls are differentially heated with a temperature difference specified, while the upper and lower walls are adiabatic. Using the Darcy model to formulate the problem, a finite difference scheme consisting of the Alternating Direction Implicit and Successive Line over Relaxation methods are used to solve the coupled non-linear governing equations. Computations are carried out for a wide range of Rayleigh number ranging from 100 to 5 × 10 3 , inclination of the walls of the parallelogram ϕ from -60 0 to 60 0 , angle of inclination of the enclosure α from -60 0 to 60 0 , aspect ratio from 0.5 to 2 and Hartmann number from 0 to 20. The flow structure and the corresponding heat transfer characteristics inside the enclosure are presented in detail. The results revealed that both the magnetic force and the inclination angle have significant effect on the flow field and heat transfer in porous medium. The reported results are in good agreement with the available published work in the literature.
