Abstract

Solar air heaters are extensively utilised in a diverse range of domestic and industrial settings. The need to enhance the thermal efficiency of solar air heaters has prompted researchers to concentrate on enhancing the thermal performance through the implementation of artificial flow modification techniques in the flow field. Consequently, the presence of this phenomenon will disrupt the laminar sublayer located beneath the absorber plate, so contributing to an elevation in the amount of turbulence within the air. Consequently, there is an augmentation in the rate of heat transmission from the absorber plate. This paper examines the impact of diverse turbulator shapes employed by researchers on enhancing the thermal efficiency of air heaters. The paper extensively examines various design factors, geometries employed, flow conditions, and their impact on turbulence, heat transfer rate, absorber temperature, and thermo-hydraulic enhancement factor. In conclusion, this study presents the last remarks and suggests future directions for further improving the performance of solar air heaters.
