摘要: Abstract In this study, thermal performance of a new solar air collector with porous absorber plate was investigated. The surface accomplished by laying out the copper meshing on absorbing plate. Hence, it aimed that could absorb more heat and boundary layer flow would be disturbed. experimental data acquired for mass rates 0.031 0.038 kg/s. efficiency determined as 25 to 57% while thermal-hydraulic calculated 14 44% depending case. It seen temperature fluid at outlet collector, useful amount pressure loss were increased rate increased. results presented increasing establishing improve collector.
