We experimentally study the nonlinear dynamics of thermoacoustic combustion oscillations in a swirl-stabilized turbulent combustor using complex network theory. We simultaneously measure the pressure fluctuations, OH^* chemiluminescence emission intensity fluctuations, and velocity fluctuations inside the combustor. We examine the spatiotemporal distribution of acoustic source clusters in a thermoacoustic power network. The driving region for thermoacoustic combustion oscillations is clearly identified by the thermoacoustic power network.
