| Outline of Final Research Achievements |
To resolve the global and regional environmental issues, developments of high efficiency and low emission combustors are indispensable. As for the gas turbine combustors, occurrence of combustion oscillations, which is still required to be understood in more detail, often prevents the development of the combustors, and hence establishments of methods for suppression of combustion oscillation are desired. In this research, characteristics of the combustion oscillation were clarified by applying dynamic mode decomposition to the results of direct numerical simulation of turbulent swirling premixed flame, and simulation of applying diode laser absorption spectroscopy was applied to the DNS results. Moreover, development of a combustion control system based on active control algorithm with the signal from diode laser absorption spectroscopy has been proceeded.
