| 摘 要： | 为了开发实际适用的富氧燃烧技术，本研究对对向流扩散火焰这一典型的扩散燃烧形态为对象进行实验考查，发现得到的实验结果与作者先前进行的数值模拟结果得到比较好的吻合，即利用详细的基元反应动力学模型对火焰的数值模拟可以很好的再现火焰特性；在此基础上利用CCD成像技术进一步研究了燃料稀释浓度、氧化剂浓度的变化对富氧空气／甲烷对向流扩散火焰形态的影响规律。

| Abstract: | In order to develop a useful oxygen - enriched combustion technology to put into actual use, counterflow diffusion flame as a basic configuration of diffusion flames was studied, and an oxygen - enriched air/ methane counterflow diffusion flame was analyzed experimentally. It could be found the trend of the obtained experimental results was as the same as the numerical results that obtained by numerical simulation before experimental study, in other words the flame characteristics can be goodly simulated by using detailed chemical kinetic. On the basis of this, the effects of flame shape that shoot by digital camera were studied when methane was diluted by dilution and the concentration of oxidant varied. |
