摘要
阐述了湍流的分形特征,应用分形理论计算了湍流燃烧速度和质量燃烧率,分析了富氧燃烧时未燃混合气密度的计算方法。借助VB语言编制计算程序,进行了计算与实验对比分析。探讨了将分形理论应用到发动机富氧燃烧模型中的可行性。
The fractal characteristic of turbulent is introduced, and the turbulent flame speed and mass fraction burnt are calculated by means of fractal theory. The calculation method for unburned mixed gas in oxygen-enriched combustion is also analysed. All the calculation results are compared with the experimental results with the aid of VB language. The feasibility of applying fractal theory to the oxygen-enriched combustion model is discussed.
