湍流和燃烧都是非常复杂的过程,两者间的非线性耦合更使问题的困难程度大大增加,因此湍流燃烧是当今工程研究领域中最复杂的研究课题之一.建立了一种用于研究湍流燃烧基础研究的新近发展起来的一种新型试验装置——可控活化热氛围燃烧器,并研究分析了其非标协流的可控活化热氛围特性.研究结果显示:非标协流可以提供协流温度范围为700~1500K、协流氧气摩尔百分比为0~21%的宽广的可控活化热氛围,同时给喷射燃烧提供了一个所谓恒定热氛围理化条件的可观的几何空间——中心半径为40mm的圆柱体范围,使得对喷射火焰在可控活化热氛围协流特性下的燃烧特性研究具有重要的现实意义.
Turbulent flow and combustion are very complex processes, and the nonlinear coupling between the two greatly increases the difficulty of the problem. Therefore, turbulent combustion is one of the most complex research topics in engineering research today, A newly developed pilot plant for controlled turbulent combustion, a controlled-activation hot-air burner, was developed to study the characteristics of controlled activation heat of non-standard co-flow.The results show that non-standard co-flow can be Provides a broad controlled heat of activation atmosphere with a co-current temperature range of 700-1500K and a co-flow oxygen mole percentage of 0-21% while providing a considerable geometric space for jet combustion with the so-called constant thermal ambience conditions - The range of cylinder with a radius of 40mm makes the research on the combustion characteristics of jet flame under the co-flow characteristics of controllable thermal atmosphere has important practical significance.
