TWO-DIMENSIONAL SIMULATION OF HYDROGEN IODIDE DECOMPOSITION REACTION USING FLUENT CODE FOR HYDROGEN PRODUCTION USING NUCLEAR TECHNOLOGY

다국어 초록 (Multilingual Abstract)

The operating characteristics of hydrogen iodide (HI) decomposition for hydrogen productionwere investigated using the commercial computational fluid dynamics code, andvarious factors, such as hydrogen production, heat of reaction, and temperature distribution,were studied to compare device performance with that expected for device development.
Hydrogen production increased with an increase of the surface-to-volume (STV)ratio. With an increase of hydrogen production, the reaction heat increased. The internalpressure and velocity of the HI decomposer were estimated through pressure drop andreducing velocity from the preheating zone. The mass of H2O was independent of the STVratio, whereas that of HI decreased with increasing STV ratio.
