摘要
在对二维线性火羽流进行理论分析的基础上,实际测量了二维线性火羽流中心线上的温度分布和速度分布,实验结果与理论分析符合得较好。实验结果表明,二维线性火羽流可以分为4个区域,除了在轴对称火羽流中出现的火焰区、间断火焰区和浮力羽流区外,还有一个过渡区域,这个区域的长度取决于线性火源的长宽比。
Based on the theoretical analysis of the line fire plumes the center line temperature and center line velocity were measured.The experimental results are very consistent with the theoretical consideration.The whole line fire plume can be divided into four regions according to experimental results.Addition to flame region,intermittent region and thermal plume region there is a transit region in axisymmetric system.The length of this region depends upon the aspect ratio of line burners.
