dc.description.abstractRib turbulators are extensively studied turbulence promoters employed in numerous industrial applications such as cooling of gas turbine blades and different electronic components, nuclear reactors and compact heat exchangers etc. for heat transfer augmentation. Some of the recent studies have shown the effect of altering rib profiles other than the square along with the effect of slit within it at fixed ratio of rib pitch to height (p/e). The present investigation focuses to explore the effects of p/e (p/e = 6, 8, 10, 12) on heat transfer augmentation and pressure penalty. Liquid crystal thermography (LCT) was applied to measure surface temperature distribution with temporal variation and ultimately the local heat transfer coefficients. Transient experiments have been conducted in an open-circuit, suction type air flow system at Reynolds number (Re) ranging from 9400 to 58850 (based on hydraulic diameter of the test section) and at a fixed value of rib height to channel hydraulic diameter ratio (e/Dh) of 0.125. The importance of current work is to appraise the potential impact of rib geometry especially the p/e ratio on the heat transfer enhancement corresponds to square solid and continuous converging slit rib configurations. It is expected, that the experimental data generated from this study will broaden the understanding of heat transfer from fundamental perspective and will serve as a benchmark dataset for validation of computational models. © Springer India 2017.-
