Innovative Volumetric Receivers Based on Selective Laser Melting Techniques (*)
[Autor: Sergio Santiago Sacristán – IMDEA Energy] Solar receivers constitute one of the key elements to achieve high thermal conversion efficiencies in concentrating solar power plants [1]. Volumetric absorbers is one category of solar receiver. Here absorbers consist of porous materials that are subjected to a high incoming radiative heat flux, absorb progressively the concentrated solar radiation inside their volume, and transfer the absorbed heat by forced convection to a working fluid passing through their structure [2, 3]. Metallic or…
