Abstract
The temperature from the tip of the methane premixed flame along the flow direction decreased dramatically at low mass flow rate of the Hexamethyldisiloxane (HMDSO) vapor while the temperature was almost constant along the flow direction at high mass flow rate of the HMDSO vapor. From the SEM images, the size of the agglomerates of silica nanoparticles had a maximum at a certain mass flow rate of the HMDSO vapor due to not only the temperature distribution along the flow direction from the tip of the premixed flame but also the temperature. Furthermore, when the concentration of the oxygen in the premixed flame increased, the size of the agglomerates decreased.
