Abstract
The double-pass solar coiliaor wilh porous media in lhe lower clnnnel provides a higher oullet tenrperqhtre
compared to conventional single-pass collec,tor. Therefore, the thermal eficiency of the solar collector is higher.
The solar colledor can be used for wide variety of applications such as solar induslrial process heal qnd solar
drying of agricultural procfucts. A theoretical model has been developed for the double-pass solar colle<:tor. An
experimental setup has been designed and construcled. Comparison ofthe theoretical and the experimenlal resulls
have bee,'t conducted. Such comparisons include the outlets tentperatnres and thennal eficiencies of lhe solar
colleclorforvqrious desigtt and operating conclilions. Close agreement has been obtained behveen lhe theorelical
