Nine decades of rocket engine and gas turbine development have shown that
thermoacoustic oscillations are difficult to predict but can usually be eliminated with …

To meet stringent NO x emission requirements, lean premixed swirling combustion
technology is widely applied in power generation and propulsion systems. However, such …

The present article investigates the interactions between the pilot and main flames in a novel
stratified swirl burner using both experimental and numerical methods. Experiments are …

In nonlinear dynamics, there are three classic routes to chaos, namely the period-doubling
route, the Ruelle–Takens–Newhouse route and the intermittency route. The first two routes …

Identifying nonlinear structures in a time series, acquired from real-world systems, is
essential to characterize the dynamics of the system under study. A single time series alone …

In many combustion devices, strong self-excited flow oscillations can arise from feedback
between unsteady heat release and acoustics, resulting in increased vibration and pollutant …

We experimentally investigate the synchronization dynamics of a self-excited
thermoacoustic system forced beyond its phase-locked state. The system consists of a …

The nonlinear behavior of thermoacoustic oscillation for premixed swirl flames fueled with
CH 4/air mixtures is experimentally studied by changing the equivalence ratio Φ, combustor …

Thermoacoustic instability is a major concern for most practical combustors such as those
used in rockets and gas turbines for propulsion and power generation. 1 The landbased gas …

We numerically study the spatiotemporal dynamics and early detection of thermoacoustic
combustion instability in a model rocket combustor using the theories of complex networks …
