| Abstract(in English) | We experimentally study the flame behavior of combustion oscillations with an off-center installed coaxial injector using information theory and complex networks. The edge flame position exhibits high-amplitude and strongly periodic fluctuations during combustion oscillations. High-amplitude fluctuations of the edge flame position induce the coherent structure of OH* chemiluminescence emission. This results in the driving of combustion oscillations. |
