Özet
The previous literature showed that there have been many studies focusing on some specific
aspects of single-pass solar air collectors, such as the effects of the number of passes, the shape of
fins and their effects on the thermal performance. Also, the effect of thermal efficiency
accompanied by the existence of these fins has been the interest of many studies. There are a few
types of research dealing with the use of porous materials (Metal foam) to improve thermal
performance. Therefore, an experimental apparatus was designed and fabricated to study the
impact of mineral foam (MF) on the efficiency of solar air collectors. The experiments were held
in Iraq, Al Ramadi climate conditions. A comparison of three configurations of absorber plates of
solar air heaters with and without MF is presented and evaluated. The results showed that by
including MF fins in the absorber plate, the absorber plate's surface area was increased, increasing
heat transmission compared to a flat plate (without MF). Moreover, utilizing MF at the tilted angle
of 45 degrees (MFθ = 45o
) increased turbulence intensity, which improved the mixing of cold and
hot air. The MFθ = 45o
layout had the best thermal efficiency of the three employed configurations
(94.8%), followed by the MFθ = 0
o
configuration (62.6%) and the flat plate configuration (33.8%),
all with the same mass flow rate. Finally, when using MF fins with a tilted angle of 45 degrees,
the air temperature differential is bigger compared to MF fins with a tilted angle of 0 degrees or a
flat plate collector.
