5-2-3 Flamelet approach を用いた多環芳香族炭化水素(PAHs)の生成過程に関する数値解析的検討

抄録

The Flamelet and Flamelet/Progress-Variable (FPV) models were applied to the numerical simulations of a laminar counterflow diffusion flame. Although the numerical results of the Flamelet and FPV models were in good agreement with the solutions based on the detailed chemistry in the temperature and mass fractions of major species, the accuracy with the Flamelet model becomes lower than that with the FPV model in mass fractions of the polycyclic aromatic hydrocarbons (PAHs). This is because progress variable used as a key parameter in the FPV model can trace the pathway of PAHs formation. Thus, the FPV model performed well to predict the PAHs formation compared with the Flamelet model.
