Abstract
Two techniques are described in this paper to analyze the dynamic and thermal behavior of a stationary air flow of forced convection in a solar collector with a perforated absorber. These perforations are vertical (plate 1) and inclined (plate inc) to the wall of insulation. Two absorber plates were used to determine the effect of absorber plate porosity as well as injection air flow rate on the collector thermal efficiency. The profiles of axial and radial velocity, velocity fields, temperature then a comparative study of the two absorber plates have been investigated.
