Experimental and CFD Evaluation of a Parallel-Flow Solar Air Heater Featuring a V-Grooved Absorber Incorporating Wire Mesh Layers Within the Downward-Pointing Channels
A unique V-grooved solar air collector was assessed experimentally and numerically to improve thermohydraulic performance. Experiments were conducted on the collector in Baghdad, Iraq, from 23 March to 3 April 2025, encompassing a mass airflow rate spanning 0.02 to 0.09 kg/s. The proposed design integrates wire mesh la...
