This paper presents a review analysis of absorber models used to improve the thermal performance in solar air heaters. Rough Surfaces and different obstacles play a key role in the improvement of thermal parameters. By review, it is identified that the impact of obstacles over the surface of the absorber plate is more than the flat surface of the absorber plate. Turbulence generated by roughened Surface and obstacles over the surface area and boundary of the channel breaks the laminar flow improving the internal temperature of the flowing air of solar air heater. In the analysis, different models of obstacles and corrugated surfaces are provided on the absorber plate. Each barrier design on absorber surface plate models impacts different parameters on the surface absorber plate in solar air heaters. Modified absorber plates with different shapes of flow breakers and flow restrictors increase the Nusselt number, Reynolds number, friction factor, and thermal efficiency in the result analysis of the review. In the present review, the different thermal parameters are analyzed through implementing various methodologies and analysis of the results done by different design model systems. By literature review study identified that the development of more accurate and efficient geometrical models with modelling absorber shapes led to the best thermal performance of solar air heaters.
