Abstract
Air jet impingement is utilized in various practical applications such as heating, cooling, and drying materials like films, textiles, cloths, and paper. It is also used in cryosurgery to cool tissues and in the food industry to cool items like biscuits and cookies. A thorough computational fluid dynamics (CFD) study was conducted to validate these applications with experimental results. The CFD analysis covered a wide range of Reynolds numbers, from 4660 to 12,000, and nozzle-to-target spacing from 2 to 6. The findings indicated that at a Y/D location of 4, a maximum velocity of 8.72 m/s was recorded, with a jet exit speed of 15 m/s decreasing to 3.76 m/s within the wall jet zone. A 56.8% decrease in axial velocity was observed transitioning from the initial phase to the wall jet region. The highest turbulence intensity was noted during the initial flow stage in the stagnation region, peaking at 3.04 m2/s2 at a velocity of 9 m/s.
