エンジン計算用すす生成モデルPS3-SMの酸素共存雰囲気下における検討

抄録

We constructed the newly soot prediction model, PS3-SM, which describes the process of PAH growth up to about 60 carbons in three sections and can predict soot production by combining with the method of moments. This model was combined with the gas phase reaction model of Miyoshi et al. which is a model for gasoline surrogate fuel including the growth process up to benzene and toluene. In this study, we improved the model under oxygen coexistence condition. As a result of model adjustments and verifications using the experimental results for a gasoline surrogate fuel measured by shock tube, it was found that the basic bell characteristics, the soot yield peak temperature and the trend of peak shift with increase of oxygen content can be reproduced well.
