Thermal-Hydraulic Performance of a Solar Flat Plate Collector Using CO2 under Superheated and Supercritical Regimes
This study presents a thermal-hydraulic assessment of an indirect solar water heating system employing carbon dioxide (CO2) as the heat-transfer fluid in a flat-plate collector. The work compares superheated and supercritical operating regimes under identical geometric, flow, and standardized outdoor conditions. A dist...
