As equivalence ratio φ increases from 0.45 to 0.50, the dynamic behavior of combustion oscillations undergoes a significant transition from low-dimensional chaos to periodic oscillation. The deterministic nature for shortly predicting the combustion oscillations sufficiently persists in the trajectories of phase space constructed from the time series of pressure fluctuations.Read More
