Functionally-graded foams for volumetric solar receivers

Journal of Physics: Conference Series, 2022
Abstract The open volumetric receiver, one of the most important components of a Concentrated Solar Power (CSP) plant, is made up by a ceramic foam on which the concentrated solar radiation impinges. Ceramic foams are employed in volumetric solar receivers because of their high specific surfaces and their operating temperatures higher ...
