要約

Large-Eddy Simulation (LES) methodology has been used to model combustion dynamics in a realistic swirling flow dump combustor. The effects of upstream velocity swirl on the combustion dynamics is investigated. A premixed flamelet model is employed to capture the interaction of the flame-front with the large-scale flow structures. It is observed that higher inlet swirl increases the overall stability of the combustion system. In addition to decreased pressure oscillations, the higher swirl reduced the flame-front oscillations and mean flame length.
