“…However, different modifications are suggested and applied to improve the heat transfer coefficient between the absorber plate and flowing air. One of the effective ways to increase the convective heat transfer rate is to increase the heat transfer area or to increase turbulence inside the flowing channel by using fins or corrugated surface [1][2][3][4][5] where many studies have been carried out in this topic. The influence of recycle on the performance of baffled double-pass flat-plate solar air heaters with internal fins attached is studied by Ho et al [6].…”

“…A number of studies have investigated the effect of different geometries of artificial roughness on heat transfer and friction factor in duct flows (Liu et al 1984, Prasad and Mullick 1985, Ouard 1989, Moummi et al 2004, Youcef-Ali and Desmons 2006, Esen 2008. Prasad and Mullick (1985) utilised a small diameter wire in a solar air heater duct to increase the transfer rate.…”

This article presents the results of the first experimental investigation of the performance of solar air flat plate collector at Biskra (latitude 34 48 0 N and longitude 5 44 0 E), Algeria. The thermal efficiency between absorber plate and air in flat plate solar collector has been enhanced by introducing obstacle rows in the dynamic air vein of the collector. For this objective, a flat plate solar collector, of 1.73 m 2 area and 25 mm air gap, has been designed and constructed. These obstacles formed with two parts: first part is perpendicular to fluid flow and the second part is inclined, they are mounted in a staggered pattern, oriented perpendicular to the fluid flow and soldered to the back plate. The solar air heater was mounted on a stand facing south at inclination angle, and it was tested under the environmental conditions. Moreover, a theoretical approach is employed for determination of the thermal performances of this collector where the temperatures of all components of the collector and outlet air are predicted. Comparisons among the experimental and theoretical results considered are reported.

“…A flow distribution in solar collector panel with horizontally inclined absorber strips was studied by Fan et al [31]. A mathematical model, to determine the thermal performance of the single pass solar air collector with offset rectangular plate fin absorber was developed by Ali et al [32,33]. Energy analysis of a solar air collector with rows of fins [34] was studied by Moummi et al Hellstrom [35] derived efficiency factors for uneven irradiation on a fin absorber.…”
