Abstract
In this study, we have applied a large eddy simulation (LES) with 2-scalar flamelet approach to a prediction of lean premixed combustion and NO production in a lean premixed combustor of 18MW class gas-turbine, L20A-DLE by Kawasaki Heavy Industries, Ltd. Validation of our result is performed by comparing with experimental data. The results show the possibility of LES with 2-scalar flamelet approach as one of the efficient analysis methods to predict phenomena in lean premixed combustion of combustor.
