In the pursuit of efficient solar collectors for sustainable energy, understanding and optimizing their performance is crucial. This research delves into the impact of rib height variations on the heat transfer properties of a flat plate solar air heater (SAH). The study investigates varying rib heights (2.5 mm, 5 mm, 10 mm, and 15 mm) in a 1500 mm solar collector, using computational fluid dynamics (CFD) simulations with ANSYS software. Results reveal a direct correlation between rib height and free stream velocity, with a maximum of 6.53 m/s for 15 mm high ribs. Velocity near the walls remains static at 0, accompanied by increased boundary layer thickness. Higher rib heights lead to a reduction in the colder region and an increase in average outlet temperature. The 5 mm rib height emerges as the most effective, reaching the highest average outlet temperature at 313.198 K. Turbulent kinetic energy profiles show a positive relationship between rib height and turbulence, with 15 mm high ribs displaying the maximum kinetic energy of 1.03m²/s². Validated through comparison with a base paper, these findings offer comprehensive insights into fluid dynamics and heat transfer in solar collectors, contributing to the design and optimization of efficient solar thermal systems.
