Abstract

The combustion of premixed H₂ and CH₄ fuels to prepare SiO₂ nanoparticles was analyzed numerically. The commercial CFD-code Fluent was used to calculate the profiles of gas velocities, temperature, species concentrations and reaction rates for various process conditions in the premixed flame reactor. To understand the effect of CH₄ addition to H₂ fuel, the CH₄ mole fraction was changed from 0% to 10%, while keeping the H₂ concentration constant. With the increase of CH₄ concentration, flame temperature increases, which will affect the properties of SiO₂ particles prepared in premixed flame reactor. Using the data of gas temperatures and velocities extracted from Fluent, the trajectories and temperature histories of SiO₂ particles were calculated inside the premixed flame reactor. This study shows that particles starting at different initial positions move inside the reactor with different particle trajectories and have different temperature histories, and the properties of SiO₂ nanoparticles prepared in the premixed flame reactor will depend on those process variables significantly.
