E107 高温場におけるアルゴン希釈がフラーレン・PAHの燃焼生成に及ぼす影響(OS1&9 マイクロエネルギー変換・熱・流動(マイクロ))

Abstract

Fullerenes were generated and observed in the combustion processes of hydrocarbon fuel under low pressure conditions although the fullerene formation mechanism from PAHs in fuel rich hydrocarbon flames under low pressure conditions has not been clarified yet. The experimental results show that the fullerene content in the total soot increases or decreases under the reduced pressure conditions when argon gas is added to the toluene and oxygen premixed gas at the constant flow rate of the premixed gas. The effects of the temperature in the combustion chamber and the argon dilution rate on the fullerene formation mechanism are discussed under various experimental conditions. The experimental results show that the fullerene contents in the total soot increase substantially by the argon dilution when the heat supply from an electric tubular heater is sufficient.
