Large Eddy Simulation of Turbulent Combustion Flows in a Methane-Hydrogen Gasturbine Combustor and NOx Prediction by its Database
In this research, the LES with the multiple-scalar flamelet approach is performed for an industrial gasturbine combustor, L30A, produced by Kawasaki Heavy Industries, which can appropriately simulate a partial premixed combustion by methane-hydrogen mixed fuel operation. Its instantaneous and time-averaged data by LES result are analyzed for predict NO production in thermal and prompt regime under different operation conditions. PDF statistical analysis is also applied to evaluate the effects from turbulent fluctuations of flame propagation and mixture fraction. These analyses reveal different mechanisms of turbulent fluctuations to increase or decrease NO productions.
