Abstract: A transient threedimensional heat transfer model is developed for a 3 kWth solar thermochemical reactor for H2O and CO2 splitting via twostep nonstoichiometric ceria cycling. The reactor consists of a windowed solar receiver ...

Abstract: We present a systematic approach to the design of a set of highflux solar simulators (HFSSs) for solar thermal, thermochemical, and materials research. The generic simulator concept consists of an array of identical radiation ...

Abstract: In this paper, radiative characterization of a packed bed of novel threedimensionally ordered macroporous (3DOM) ceria particles is performed in the spectral range relevant to solar thermochemical processes, 0.35–2.2 خ¼m. ...

Abstract: Heat transfer is predicted for a solidsolid heat recuperation system employed in a novel directlyirradiated solar thermochemical reactor realizing a metal oxide based nonstoichiometric redox cycle for production of synthesis ...

Abstract: The University of Minnesota's high flux simulator delivers radiative power of approximately 9.2 kW over a أک60 mm circular area located in the focal plane, corresponding to an average flux of 3200 kW m−2, with a ...

Abstract: The redox chemistry of nonstoichiometric metal oxides can be used to produce chemical fuels by harnessing concentrated solar energy to split water and/or carbon dioxide. In such a process, it is desirable to use a porous ...

Abstract: The design procedure for a 3 kWth prototype solar thermochemical reactor to implement isothermal redox cycling of ceria for CO2 splitting is presented. The reactor uses beds of mmsized porous ceria particles contained in ...
