我们从非线性动力学的角度从瘦肉预混合气动燃烧器中燃烧不稳定性的动态行为进行了实验研究。非线性时间序列分析与替代数据方法结合使用，清楚地表明，随着等效比的增加，燃烧不稳定性的动态行为经历了从随机波动到周期性振荡，通过低维混乱的振荡的显着过渡。我们还表明，一种非线性预测方法可用于预测瘦的预混合气盘燃烧器中燃烧不稳定性的短期动态行为，该燃烧器尚未在燃烧科学和物理学领域解决。 （c）2011年美国物理研究所。 [doi：10.1063/1.3563577]
We experimentally investigate the dynamic behavior of the combustion instability in a lean premixed gas-turbine combustor from the viewpoint of nonlinear dynamics. A nonlinear time series analysis in combination with a surrogate data method clearly reveals that as the equivalence ratio increases, the dynamic behavior of the combustion instability undergoes a significant transition from stochastic fluctuation to periodic oscillation through low-dimensional chaotic oscillation. We also show that a nonlinear forecasting method is useful for predicting the short-term dynamic behavior of the combustion instability in a lean premixed gas-turbine combustor, which has not been addressed in the fields of combustion science and physics.
