Abstract

The use of modern tools of computational fluid dynamics for investigation the pulsation processes in the combustion chamber caused by the design features of flame tubes and aerodynamic interaction compressor, combustor and turbine is discussed. Purpose. Investigation and forecasting of non-stationary processes in gas turbine low-emission combustion chambers using mathematical modeling. Design/methodology/approach. The numerical experiment by definition of pressure pulsations level in the gas turbine combustion chamber is performed. The results of the numerical experiments using a three-dimensional mathematical models in gaseous fuels combustion chambers are adequately reflect the physical and chemical processes of unsteady combustion and can be recommended for optimizing the geometrical and operational parameters of low-emission combustion chambers. Findings. According to the results of three-dimensional calculations, the maximum amplitude fluctuation arising in the flame tube and the annulus gas turbine combustion chambers are defined. Originality/value. The application of such mathematical models for the creation new samples combustors operating at a lean air-fuel mixture as well as the modernization of the existing cameras to develop constructive measures aimed at reducing the likelihood of pulsation combustion modes, is advisable.
