A three-dimensional (3-D) numerical model for simulating the process of solar thermochemical splitting of carbon dioxide (CO2) into carbon monoxide (CO) in a counter-rotating-ring receiver/reactor/recuperator or CR5 are developed in order to account for three-dimensional effects such as edge effect of side walls. The present 3-D model, which is based on our previous two-dimensional first-generation model, takes into account heat transfer, gas-phase flow, multiple-species transport in open channels and through pores of the porous reactant layer, and redox chemical reactions at the gas/solid interfaces. Sample computed results (e.g., temperature distribution, species concentration contours) are presented to illustrate model utility. The model is employed to examine the effects of rates of CO2 and argon neutral gas injection and the redox chemical reactions on thermochemical solar conversion efficiency. Effects of the CR5 width and argon neutral gas injection on O2 crossover are also explored.
