In this article, a computational model was developed to examine the effect that the vortices have on heat transfer and system performance for a range of Reynolds numbers of 100 to 800.Abstract:
The use of vanes in grooved channels for heat transfer enhancement has received more attention in the recent years due to applications in heat exchangers and electronics cooling. The current work focuses on characterizing the vortex formation around heated elements in grooved channels with curved vanes. A computational model is developed to examine the effect that the vortices have on heat transfer and system performance for a range of Reynolds numbers of 100 to 800. These vortices explain the previously observed characteristics in system performance for geometries with the use of curved vanes. At a Reynolds number of 400 these vortices inhibit heat transfer and increase pressure drop in the channel, resulting in significant decreases in system performance.© 2003 ASMEread more

Optimum Placement of Heated Blocks in Laminar Forced Convection
TL;DR: In this article, a parametric study of the different choices for interblock spacing is performed numerically using the finite volume method, and the results show that simple upstream crowding of blocks decreases the global maximum temperature in the channel by up to 6.83%.
