摘要: Abstract To perform thermochemical cycles using non-volatile metal oxides to split water and produce hydrogen, a directly irradiated fluidized bed reactor is designed fabricated for beam-down configuration. As the main aim of this investigation analyze heat transfer particulate flow reactor, chemically inert particles are used. A transient 3D mass model formulated by combined approach discrete element method computational fluid dynamics. The radiative solved ordinate radiation model. Experimental validation accomplished measured temperatures, obtained with prototype tested under 30 kWth high-flux solar simulator. applied granular characteristics efficiency various superficial gas velocities masses. results indicate that higher rate increases velocity convection loss decreases temperature reactor.
