Abstract
The distribution of concentrated solar irradiation has a significant impact on temperature distribution in solar reactors. In this way, the objective of this paper is to analyze the thermal performance of a fixed-bed solar thermochemical reactor through a mathematical model. Partial differential equations formed this model and were transformed into ordinary differential equations by the finite difference method. In addition, a code in the Mathematica software with NDSolve was used to obtain the results. Furthermore, to carry out the investigation of the thermic behavior of radiation and temperature distribution, the Rosseland approximation was used. Thus, the typical influences of the radiation heat flux, porosity, emissivity, and temperature distribution were investigated.
