Abstract
A study was conducted to determine the heat transmission rate and friction properties of a solar air heater's (SAH) absorber by including c-shaped rib, with and without perforations, and the efficiency of this absorber with and without zeolite coating was investigated. This research is carried out by varying Reynolds numbers (Re) ranges between 3000 to 18000, height of the C-shaped rib (e) ranges between 2 mm to 4 mm, and the embedded hole diameter in the c-shaped rib ranges between 1 mm to 3 mm. The impact of rib height, hole diameter, and zeolite coating on thermal efficiency and Nusselt number is compared to a flat channel under the same flow environments. A strong secondary flow is created by the free shear layer reattaching more often at higher rib heights, and a smaller hole can exaggerate heat transfer and enhance the cross-flow effect. The thermal efficiency and Nusselt number of the solar air heater with c-ribs (Rib height = 4mm and hole diameter = 1mm) and zeolite coating on the absorber increased by 29.67% and 62.16% over the flat absorber. Ribs 4mm high can increase duct friction by up to 3.1 times compared to a smooth duct.
