Development and testing of a volumetric gas receiver for high-temperature applications

Experimental Characterization of a High-Temperature, High-Flux, Solar Volumetric Receiver

“…This results in a weighted least-square functional being defined as (8) To rmrurmze this functional (which minimizes the weighted sum of the squares of the residuals), it can be differentiated with respect to the parameters ( f31' f32' ••• , f3 p ) in the model and set to zero. This leads to (9) or (10) where V/l = a vector operator X = sensitivity coefficient matrix …”

“…Another major effort by Atlantis Energy Limited (Bern, Switzerland) has been made using a ceramic grid-type absorber. They have completed tests on a 500-kW prototype receiver reported by Posnansky and Pylkkanen [10] and Pylkkanen and Posnansky [11]. For a more exhaustive literature review of both thermal and chemical reaction solar volumetric receivers, see Hellmuth [5].…”

Digital design and 3D printing of innovative SiC architectures for high temperature volumetric solar receivers

“…The heat transfer fluid can be used pressurised or at atmospheric pressure. In theory, when the fluid is pressurised, the energy yields of the receivers are greater [17,18] but the design of the window, which keeps the fluid circuit closed while allowing the Sun's rays to pass through, is very difficult to achieve [19,20]. Finally, the advantage of receivers at atmospheric pressure is their lower cost due to their less complex implementation.…”
