In the past, transverse surface grooves have shown promise in heat transfer augmentation. These lead to the formation of free shear layers and traveling waves, which augment convective transport normal to the passage walls. In the current work, two-dimensional Navier-Stokes simulations of heat and momentum transport using the spectral element technique are used to investigate the heat transfer and fan power performance of the developing regions of finite-length, grooved channel passage arrays. This study also considers the accelerating and decelerating flows entering and exiting the arrays. The computational domain has in inlet region followed by two passages stacked one above the other with thirty contiguous transverse grooves cut symmetrically into opposite walls and then a sufficiently long exit region that allows pressure recovery to take place. The performance metrics defined in the work include the average array Nusselt number and the total required fan power. The performance of the grooved channel arrays is compared with that of flat passage arrays with the same average wall center-to-center spacing (equal flow volume) for the Reynolds number range 1000 to 3000. The addition of grooves improves the overall heat transfer by a factor of 1.46 at Re =1000 and by a factor of 2.75 at Re =3000. The current calculations will provide guidance for future three-dimensional calculations of heat transfer versus fan power performance of developing flow within grooved passage arrays. Earlier studies show that three-dimensional results more accurately reproduce experimental results for Reynolds numbers greater than roughly 600.

Book Synopsis Forced Convection Heat Transfer in Passages with Accelerating Turbulent Flow by : Seid Ali Rishehri
Download or read book Forced Convection Heat Transfer in Passages with Accelerating Turbulent Flow written by Seid Ali Rishehri and published by . This book was released on 1973 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In turbulent boundary layers it has been suggested that if the fluid is accelerated in the main flow direction, the whole flow structure may undergo a partial or complete decay to laminar; some depression in convective heat transfer is experienced and the usual turbulent boundary layer theories fail to produce a satisfactory solution. The effects of acceleration on heat transfer in confined flows has received comparatively less attention. In this thesis, these effects are investigated and suitable thermal boundary conditions under which no other significant influence apart from acceleration is encountered, are determined. This is initially discussed with other considerations regarding the effects of velocity profile on heat transfer, as well as some theoretical investigation of a simple turbulence model applied to the problem. Based on a dimensional argument, an acceleration parameter has been proposed and its ability to provide some guide to the effects of moderate and severe acceleration is demonstrated. The experimental programme has been carefully designed to comply with the theoretical findings and in particular the requirement for special heat flux boundary conditions.......
