Shape optimization for absorber plates of solar air collectors

Experimental investigation of thermal performance of solar air heater having different obstacles on absorber plates

“…The modifications to improve the heat-transfer coefficient between the absorber plate and air include the use of an absorber with fins attached, corrugated absorber, matrix type absorber, with packed bed, with baffles and different configurations are given in the literature [2][3][4][5][6][7][8][9][10][11][12][13].…”

Solar powered air conditioning system using rotary honeycomb desiccant wheel

“…By comparing the previous equation with Eq. (9) and by assuming that the transmissivity absorptivity factor equals 0.85 [18]. The equation takes the following form Z ¼ 0:95ð0:85 À 13:3 T coll À Ta ð Þ =GÞ.…”

Dynamic thermal performance analysis of two solar air collectors with and without porous media

“…The shape of the absorber plate in solar air collector is the most important parameter in the design of the collector. Moreover, the increasing of the absorber shape area will increase the heat transfer to the air [8,9].…”
