An Evaluation of Premixed Combustion around a Bluff Body Using a Combustion Model

概要

論文の詳細を見る
A numerical simulation of a premixed flame stabilized by a bluff body was performed using the LES(Large Eddy Simulation)turbulent model and a turbulent combustion model which was developed through an evaluation of a local quenching effect due to flame stretching. The latter model also includes the temperature effect of unburned gas and the pressure effect in a combustor. Due to the strong organized motion created by the bluff body, fluctuations of the premixed flame could be seen. Furthermore, the distributions of the time-averaged velocity, temperature and intensity of the velocity fluctuation were compared with experimental data and found to be in good agreement.
