“…Indeed, Vijayan and Arjunan [17] studied the thermal performance of indirect forced convection solar dryer with the air mass flow rate of 0.058 kg/s, and the thermal efficiency of the collector is observed in the range of 20 % to 32 %. Aissaoui et al [22] presented an experimental and theoretical analysis on thermal performance of the flat plate solar air collector, and the thermal efficiency of this collector is observed in the range of 22.5 % to 40 % at air mass flow rate of 0.1324 kg/s. Bakari [8] studied the thermal efficiency of air flat plate solar collector with different numbers of baffles.…”

Article presents an experimental investigation for the comparison of thermal performance of three different configurations flat plate solar collector. These flat plate solar collectors consist of glass cover and aluminium absorber plate which is painted with black paint. The edge and bottom surfaces are thermally insulated with a polystyrene layer for the first configuration, a polystyrene layer covered with a sheet of aluminium paper for the second one and a polystyrene layer covered with a sheet of aluminium paper and containing baffles for the third configuration. In this experiment, thermal efficiency of flat plate solar collector integrated with baffles was studied and compared with the two ordinary flat plate collectors. The results showed that integrating flat plate solar collector with baffles significantly increased the thermal efficiency of the system. It was noted that a mean thermal efficiency is 20.3 %, 29.8 % and 35.1 % for the first, second and third configuration, respectively. The results show a maximum temperature rise of 23.5 °C, 31.6 °C and 34.6 °C with respect to the inlet air temperature, for the first, second and third configuration, respectively. Baffles improve the thermal performance of the flat plate solar collector by increasing the outlet temperature.

“…The maximum and minimum collector efficiency for SAC with black and white coloured absorber was found to be 85% and 54%, respectively. Aissaoui et al [4] studied the performance of a flat plate SAC both experimentally and computationally. The thermal efficiency was found to vary between 22% and 40%.…”

“…Mixed convection problems in cavities are studied by several researchers in last two decades due to a range of applications. The combined convection flow and heat transfer in cavities find its applications in food processing and float glass production, solar collectors, lake and reservoirs, nuclear reactors, solar ponds and crystal growth [1][2][3][4][5].…”

Numerical study has been performed to investigate the combined effects of lid movement and buoyancy on flow and heat transfer characteristics for the mixed convective flow inside a lid-driven arc-shape cavity. The work is motivated by its immense importance due to its wide range of applications. The numerical simulations, therefore, are performed for three different shape concave enclosures (rectangular, circular and triangular) in laminar flow regime and for different Reynolds numbers (10 ≤ Re ≤ 1000) and Grashof numbers (10 4 ≤ Gr ≤ 10 7 ) effects on the flow and heat transfer. Numerical results are presented in terms of streamlines, isotherms, velocity profiles and average Nusselt number along the bottom wall. The comparisons showed that the increase of Reynolds and Grashof numbers enhance the heat transfer for all forms of alveolus. Further, triangular alveolus highlights a higher heat transfer rate for higher Re numbers.
