Description
Summary:New oblique fins with corrugated edges to incorporate into the rectangular channel have been suggested in current work to boost heat transfer. Current investigation aims to introduce and analyze an oblique-finned corrugated (OCF) to numerically evaluate a unique method for improving heat transfer. Vertical gap ratios (V) of 0.15, 0.20, and 0.25; horizontal gap ratios (H) of 0.03, 0.04, and 0.05; and oblique-angle (θ) values of 10°, 20°, and 40° are just a few of the design factors that are examined. The results show that the Nusselt number enhances by 73.5%, 74%, and 73.2% across the same range of Reynolds number at a group of gap ratios (V = 0.15, h = 0.04), (V = 0.2, h = 0.05), and (V = 0.25, h = 0.05), respectively. Besides, the design parameters V = 0.15, H = 0.05, and θ = 40° yielded the best PEC of 2.437. New correlations for the innovative oblique-finned corrugated model are also presented.
