Analytical study of exergetic efficiency of a solar air heater with C-shape roughness element

Year: 2024

Type: article

Abstract: This study analytically evaluates the exergetic efficiency of solar air heaters incorporating C-shaped rib roughened absorber plates. Compared to flat plate designs, the proposed geometry significantly enhances energy performance. Optimal roughness parameters for maximizing exergy efficiency are identified, providing design guidelines for improved solar air heater systems. The maximum value of exergy efficiency of the solar air heater, with C-shaped ribs was obtained as 5.9%.
