“…The primary goal of this research is to examine how corrugation angle affects heat transport. Moneim et al [ 10 ] carried out an experimental investigation on how V‐shaped ribs in a rectangular duct affected the outcomes. They experimented with several V‐shape angles of 30°, 45°, and 60° and found an increase with angle.…”

Solar energy is a clean and sustainable source of power generation. There are various industrial and domestic applications of Solar Air Heaters (SAHs), but their low thermal efficiency poses a challenge. To improve thermal efficiency, a novel‐angled corrugated jet‐impinging channel has been proposed for the absorbing plate of SAHs. A numerical study has been performed for four different arrangements of jets, i.e., single circular, single square, 2 × 2 square, and 3 × 3 square jet array with four channels, i.e., 30°, 45°, 60°, and 90° corrugated over the Reynolds number range of 1600–2700 for the jet to target plate range of 4.9–15. It is observed that multiple jets impinging increases the heat transfer significantly. The optimization has been performed by instigating the parametric study. Flow and thermal profiles are studied. The 45° corrugated target plate with 3 × 3 multiple jet impingement, 4.9 jet‐to‐target plate distance, and 2700 Reynolds number is chosen to have the best thermal efficiency. A Thermal Performance Factor of around 8 was achieved as compared to the base case.

“…Besides arrangement of ribs, angle of ribs was also studied in the past. Abdel-Moneim et al [24] investigated the amplification of heat transfer and the effect of flow friction using a rectangular duct with V-shaped ribs at three different angles (i.e., 30 • , 45 • , 60 • ) at the bottom wall. Experiments were performed at Reynolds number ranging from 15000 to 75000 at a rib-to-pitch ratio between 0.0375 and 0.15.…”

Heat transfer augmentation has become the utmost industrial desire. Turbulence promoters seems to be a better option for better heat transfer but at the expense of enormous pressure drop. In the current study, experimental optimization of heat transfer and pressure drop in various configurations of ribbed and corrugated surfaces on the bottom wall of the Solar Air Heater channel, having aspect ratio of 26:5 was performed. The results were evaluated in terms of enhancement in heat transfer (Nu/Nu s ), friction factor ratio ( f / f s ) and thermal performance factor (η). Three different cases and nine configurations with a pitch to rib/corrugation height ratio of 4.0 were studied. Case A consists of a smooth, continuous square rib, inline and staggered broken ribs. Case B comprises 30 • , 45 • , 60 • and 90 • trapezoidal corrugated geometries while case C is the comparison of smooth, wavy corrugated and the best configurations of cases A and B. The results show that rectangular duct with staggered broken ribs and trapezoidal corrugation at 45 • are the best configurations for case A and B, respectively. The 45 • corrugated configuration is the best one amongst all, with values of 1.53, 1.5 and 1.33% for Nu/Nu s , f / f s and η respectively. Nomenclature Abbreviations CNCComputer Numerical Control config. Configuration correl.
