| Abstract: | The effects of various concentrations of nanoaluminum powder and surfactant (oleic acid) on the ignition characteristics of heptane-based nanofluid fuel as suspend droplets were investigated. Two thermocouples were employed to measure the droplet temperature and the gas temperature near the droplet when the resistance furnace temperature was 500℃. The results showed that the ignition temperature increased significantly with the increase of oleic acid concentration. The ignition temperature decreased significantly with increasing nanoaluminum concentration. |
