Insight Into

Production of hydrogen using solar thermal energy has the potential to be a viable alternative to other hydrogen production methods, typically fossil-fuel driven processes. Thermochemical reactions for splitting water require high temperatures to operate effectively, for which solar is well-suited. Numerical modeling to investigate the concept of a solar-driven reactor for splitting water is presented in detail in this paper for an innovative reactor, known as the “counter-rotating-ring receiver/reactor/recuperator” (CR5) solar thermochemical heat engine that is presently under development. In this paper, details of numerical simulations predicting the thermal/fluid behavior of the innovative solar-driven thermo-chemical reactor are described in detail. These scoping calculations have been used to provide insight into the thermal behavior of the counter-rotating reactor rings and to assess the degree of flow control required for the CR5 concept.

Real Process

A mathematical model of the process of ozone oxidation of nitrogen oxides in a chemical reactor is presented. The conformity of the model to the real process is checked by comparing the results of calculations with the data of physical experiments on a laboratory installation. The results of numerical modeling of the process in the reactor using the specified mathematical model are presented. The results of the calculations revealed the influence of the initial parameters of the process on its performance characteristics, in particular on the efficiency of conversion of nitrogen monoxide into dioxide. Based on the analysis of the calculated characteristics, the optimal operating parameters of the reactor at different modes are determined. Bibl. 5, fig. 6, table. 4.
