Abstract
Fluid flow and heat transfer characteristics were analyzed for a constant property fluid flowing laminarly through a parallel plate channel with staggered, transverse ribs and a constant heat flux along both walls. After a finite entry length the flow becomes periodically fully developed. Computations were carried out in the fully-developed regime for different Reynolds numbers, Prandtl numbers, and geometric arrangements. It is found that significant heat transfer augmentation is obtained for high Prandtl number fluids such as water or fluorocarbons. In addition, conduction in the channel walls is found to play a highly beneficial role in enhancing heat transfer.
