| Research Abstract |
In this study, to develop the turbulent combustion model which can compute combustion in a combustor more precisely and which is available for the development and design of a combustor, direct numerical simulations(DNS) of turbulent combustion were implemented with considering the behaviours of chemical species on the wall and between the gas and wall in a combustor, which has never been considered. As a result, it is found that when the behaviours of chemical species on and near the wall are considered, the flame quenches on the wall and the heat release rate does not increase nearby, and the DNS data of combustion computation with more realistic conditions for the inside of a combustor was obtained.
