In this article, we optimize the performance of a solar air heater (SAH) using two designs and computational fluid dynamics (CFD) analysis in this article. With the help of ANSYS fluent, two designs are considered to investigate the effect of different rib heights (e = 1, 1.2, 1.4, 1.6, and 1.8) and duct depths (h = 16, 18, 20, 22, and 24). The effects of dif-ferent parameters such as velocity, temperature, turbulence kinetic energy, and turbu-lence energy are compared to optimize the performance of designs 2 and 3. It is noticed that except temperature, all other parameters are on the lower side for design 2 as compared to design 3, due to improper air mixing in design 2. The authors presented the optimized design 3 with rib height e = 1.8 and depth of duct h = 16 after consideration of all the parameters (temperature, velocity, turbulence kinetic energy, and turbulence intensity) at various rib heights and depths of duct. These numerical results will serve as a benchmark for future research to improve the efficacy of solar air heaters.
