This study experimentally investigates Triply Periodic Minimal Surfaces (TPMS) as structured porous media for concentrated solar power systems. Two mock-up planar receivers with different TPMS lattices, Diamond and SplitP, were fabricated using Additive Manufacturing. Testing was conducted within the SFERA III project, funded by EU, utilizing a simulator facility at IMDEA Energy Institute in Madrid, Spain. Thermal performance evaluated under varying mass flow rates heat flux levels,...
An experimental study was carried out to assess the performance of a tubular absorber enhanced with Raschig Rings (RR) porous medium for CSP applications. Two alternative designs different lengths 20 and 40 mm were fabricated compared two conventional tube without surface coating. Several tests conducted at solar furnace SF60 Plataforma Solar de Almería (PSA) within international access program SFERA III project, financed by EU. The main scope provide comprehensive detail on hydraulic...

Abstract Porous media are typically capable to enhance heat transfer, at the cost of an increase pressure drop, mainly in view huge surface wetted by fluid. In this work, a tubular receiver for CSP applications, partly filled with porous medium constituted packed bed copper Raschig Rings is investigated first time. The analysis, carried out numerically, aims studying detail mechanisms transfer from wall gaseous fluid (air) through metal matrix symmetric and asymmetric heating conditions....
