| Abstract | This study explores the transient heat transfer characteristics of two-dimensional air-jet impingement on a heated surface. Utilizing numerical methods, the research comprehensively analyzes thermal behavior and transient heat transfer mechanisms, considering varied jet parameters, plate temperatures, and time. The investigation covers Reynolds numbers (Re) in the range of 3000 to 12000, based on the hydraulic diameter, with nozzle diameters (Dj) of 3mm, 4mm, and 5mm. The nozzle jet-to-plate distance (H/D) is varied from 0.2 to 2. Results reveal substantial variations in Nusselt numbers (Nu) corresponding to changes in Re and jet-to-plate distance. In addition, approximately Re 12000 the largest friction factor occur at 3mm jet diameter. The Notably, heat transfer near the stagnation point intensifies with decreased jet-to-plate distance, while heat transfer near the boundary point diminishes. These findings offer valuable insights for practical applications in thermal management and heat exchanger design. |
