Effects of Surface Reactions and Nucleation Reactions on Soot Formation in Soot Particle Generation Model

すす粒子生成モデルにおける表面反応および核形成反応がすす生成特性に及ぼす影響

The authors computed the primary soot particles generation in a shock tube pyrolysis with toluene/n-heptane and toluene/iso-octane mixtures by Alexiou et al. Calculated soot yield using latest elementary reaction model was exceeded the experimental one. It is assumed that nucleation reactions and acetylene addition reaction were the primary factors. Because those chemical reaction rates have some uncertainty, the soot generation characteristics were investigated by changing the chemical reaction rates of nucleation reactions and acetylene addition reaction.トルエンにイソオクタンまたはノルマルヘプタンを混合した2 成分混合燃料について,すす生成量に関する計算を実施した.計算値は衝撃波管で得られた実験値を上回った.計算値過大の要因として,核形成反応およびアセチレン表面付加反応に着目した.各反応速度定数を変化させ,すす生成特性に及ぼす影響について検討した.
