dc.description.abstract1Introduction: The paper is devoted to investigation of gaseous fuel burning stability in low emission combustor of stationary gas turbine engine (GTE). The mathematical model of unsteady processes in GTE low emission combustor is developed. A methodology of numerical experiment concerning stability of gaseous fuel burning in low emission combustor with using complex of computational fluid dynamics (CFD) is proposed. Theoretical studies of non-stationary processes in a low emission gas turbine combustor were performed using the Large Eddy Simulation (LES) model of turbulence. The results of the model verification confirm its validity for the wide spectrum of fuel nozzle design. The performed 3D calculations allowed defining main pulsating features of a low emission gas turbine combustor. For the entire considered frequency range, a pronounced frequency of 189 Hz is traced, which is caused by combustion processes, as evidenced by the spectra of temperature fluctuations and the mass concentration of fuel. The calculated local mean square pulsations of the static pressure inside the combustion line can reach maximum values of about 11.5 kPa. The obtained results and recommendations can be used for modeling of unsteady processes in low emission combustor and stability improvement of GTE combustor with partially premixed lean fuel-air mixtures.
