| 摘 要： | 引入一种图像处理技术和非线性时间序列分析方法对生物柴油喷射火焰的燃烧不稳定性进行了分析.燃烧室内火焰二维图像的灰度值分布一定程度上反映了燃烧温度的分布状态,通过经典的关联维数方法和最大李雅普诺夫指数方法对这种灰度值时间序列进行分析比较,结果发现火焰混沌显然存在于燃烧不稳定过程之中.

| Abstract: | Introduce an image processing method and nonlinear time series analysis technology to study bio-diesel jet flame instability in combustion chamber.The gray value of two-dimensional flame image reflects the distribution of the temperature in combustion chamber,compared with the classical methods of correlation dimension and the largest Lyapunov exponent.It is found that flame chaos is obviously existed in the combustion process. |
