我们的重点是研究燃烧噪声的时间动态。具体而言，本文首次利用递归分析方法研究了预混合湍流射流火焰直接燃烧噪声的动力学特性。分析表明，燃烧噪声具有不规则间隔周期窗的特征。通过比较，得出了不同等效比下声压时间轨迹的差异。
We focus on investigating temporal dynamics of combustion noise. Specifically, the dynamics of direct combustion noise, emitted from a premixed turbulent jet flame are studied for the first time with the help of recurrence analysis. The analysis showed that combustion noise is characterized by irregularly spaced periodic windows. Comparisons are carried out to bring out differences in the time trace of acoustic pressure for different equivalence ratios.
