Study on Formation Characteristics of Polycyclic Aromatic Hydrocarbons in Non-Premixed Flames of Toluene Reference Fuel

Toluene Reference Fuel 火炎における芳香族炭化水素の生成特性

Polycyclic aromatic hydrocarbons (PAHs) are itself exhibit carcinogenicity and believed to be precursors of the particulate matter. In this study, measurements of the particle volume fraction (PVF) and the mole fractions of PAHs were carried out for counter flow diffusion flames of iso-Octane and Toluene reference fuels. PAHs are measured by using the Thermal Desorption - Gas Chromatography / Mass Spectrometry system. Experimental results were compared with numerical results calculated by using the KAUST 1 model, the CRECK model and the P.AN model. In this paper, oxidation and decomposition reactions of Benzo [e] Pyrene, Benzo [ghi] Perylene, Coronene and Perylene were added into the KAUST 1 model. As results, it was shown that the CRECK model shows good reproducibility of PVF and PAHs mole fraction profiles. Although the KAUST 1 model shows differences in PVF profiles, there is room for improvement by adjusting the surface reactions. Since the KAUST 1 model is extremely smaller than the CRECK model, it can be thought of as a model suitable for engine simulations.本研究では,対向流拡散火炎を用いて,燃料組成が多環芳香族炭化水素生成特性に及ぼす影響を調べた.燃料にはイソオクタンおよびイソオクタン・ノルマルヘプタン・トルエン混合燃料火炎を用いた.実験結果に基づき,異なるサイズのすす予測モデルの検証,修正を行い,エンジンシミュレーションに適したモデルの評価を行った.
