| Outline of Final Research Achievements |
In this study, I researched and proposed a new method to construct a database based on Tabulated Chemistry. Simulations were performed considering temperature fluctuations during pyrolysis, and it was found that the effect of temperature fluctuations is negligible. Detailed kinetic mechanism and the sectional method coupled with computational fluid dynamics (CFD) were compared with Tabulated Chemistry and sectional method coupled with CFD simulations. The results showed that simulation with Tabulated Chemistry was faster by a factor of 20 than that with detailed kinetic mechanism.

本研究の目的は，Tabulated Chemistryの熱分解への適用可能性を大きく広げることであ
る． Tabulated Chemistryに基づく手法であれば，計算コストを数千～数万分の一に削減できる．Tabulated Chemistryに基づく簡略化で先行する燃焼の分野では，その研究例が豊富である．しかしながら，燃焼が発熱反応で火炎面において局所的に激しく反応が起こるのに対し，熱分解は吸熱反応であり装置全体における反応が等しく重要である．
