摘要
火焰燃烧的好坏直接影响排放的高低,火焰前锋面的影响因素十分复杂,且各因素之间相互关联、互相影响。因此,研究火焰前锋面的影响因素显得十分重要。文章所涉及的影响因素包括:EGR率、湍流强度和火核半径、混合气的当量比、混合燃料、路易斯数和火焰前锋面处密度梯度和火焰前锋面厚度,并对日后发展做出展望。
The quality of flame combustion directly affects the level of emission. The factors affecting the front of flame are very complex, and the factors are interrelated and influence each other. Therefore, it is very important to study the influence factors of flame front. The influencing factors involved in this paper include: EGR rate, turbulence intensity and core radius, equivalence ratio of mixture, mixed fuel, Lewis number, density gradient at front of flame and thickness of front of flame, and the future development is prospected.
