Numerical analysis on premixed combustion of H2–SiCl4–Air system to prepare SiO2 particles

In this study, we used the commercial CFD-code FLUENT to analyze numerically the hydrogen combustion and SiO2 particle formation in the premixed flame reactor. We considered SiCl4 as a precursor for SiO2 particle formation and calculated the profiles of fluid flow, temperature, species concentration and reaction rates for 2D premixed reactor model in FLUENT. Using the data for temperature and velocity extracted from FLUENT, we calculated the trajectories and temperature histories of SiO2 particles moving inside the premixed flame reactor and those particles starting near the centerline of reactor pass through the maximum temperature histories.
