Abstract

The effect of phase changes on the combustion of single metal particles was analyzed. It was observed that the free-falling monodisperse molten metal droplets are formed at a repeatable initial temperatures and velocities between a cold tool cathode and a consumable wire anode. The temperature histories of the ignited and burned droplets formed in the oxygenated environments were studied using optical pyrometry. It was observed that dissolution of oxygen and other gases occurs within the combustion regimes. The correlation between the burning particle temoperature and composition histories was identified.
