Application of entransy theory in the heat transfer optimization of flat-plate solar collectors [PDF]
Chinese Science Bulletin, 2012 The flat-plate solar collector is an important component in solar-thermal systems, and its heat transfer optimization is of great significance in terms of the efficiency of energy utilization. However, most existing flat-plate collectors adopt metallic absorber plates with uniform thickness, which often works against energy conservation. In this paper,
