A roughness of the absorber plate can improve the efficiency of a solar air heater. To boost
the efficiency of triangle solar air heaters, this research presents the results of a comparison …

Solar heating is a low-cost option for heating buildings, which help in the development of a
sustainable built environment as it can fulfil the building heating demand. For this purpose …

The performance of a solar air heater roughened with sine wave baffles has been calculated
in terms of effective and thermal efficiency. Relative baffle length (L b/LP), relative roughness …

Heat transfer systems have been employed in numerous industrial and residential settings
to convert and recover heat. One effective approach for enhancing heat transfer rates …

This research explores enhancing the efficiency of a solar air heater (SAH) by integrating
cone-perforated channels as roughness features on the absorber plate. Two configurations …

Energy is the key driver of life. It is required for the growth, exaltation, modernization, and
