Özet
The thermal decomposition of methane represents a significant pathway for producing high-purity hydrogen. Aerosol flow reactors, particularly when coupled with concentrated solar energy, are considered highly suitable for this thermochemical process. This study presents a comprehensive Computational Fluid Dynamics (CFD) model of methane decomposition within an aerosol flow reactor. The model integrates coupled phenomena, including gas flow dynamics, chemical reaction mechanisms, radiative and convective heat transfer, and a discrete phase model for carbon particles. The development of a generalized, predictive model is crucial for reactor optimization, and CFD modeling offers rapid prediction capabilities. Consequently, this work validates a novel CFD model against previously published experimental and theoretical data from an Aerosol Quartz Flow Reactor (AFR). The model computes methane decomposition rates and the spatial dispersion of components (H2, C, CH4) under various feeding rates and temperature profiles.
