内燃机燃烧火焰的分形特征研究

Investigation on Fractal Characteristics of Flame Surface of Combustion in an Engine

介绍了发动机湍流预混燃烧火焰分形研究的进展,分析了湍流火焰分维测量的数盒子法、修正数盒子法及其优缺点,讨论了火焰特征尺度、内外截点的尺度及维数D与各参数之间的关系。

In this paper, the recent progresses in the measurement of fractal dimension are reviewed. Evidences, methods and the findings of the fractal dimension measurement are included. Box-counting, revising box-counting and their application restriction are introduced in detail. The findings researched by several researchers on fraetal measurement, flame characteristic dimension, dimensions of in-point and out-polnt, and the relationship between fractal dimension D and all parameters are also discussed.
