| 摘 要： | 近期液雾火焰结构的研究表明,在很多情况下在液雾火焰中燃油液滴并不是以单滴形式烧掉,蒸发液雾形成蒸汽空气雾在稠液雾边界上以扩散火焰方式燃烧掉。这个结果强调了在热环境中液雾蒸发的重要性。基于对单滴蒸发的研究金与Lefebvve导出液雾蒸发模型,在跨流喷射的液雾问题中,已经成功地运用了这个液雾分析模型。这个模型得出

| Abstract: | Based on studying interdependence of spray characteristics and evaporation history of fuel sprays and on measuring the spray characteristics by light scattering in heated air stream,authors conducted an experimental and analytical research on variation of spray characteristics of vaporizing kerozine sprays in a straight cylindrical vaporizer with heated air stream. The fuel was injected co-axially from a plane orifice air blast atomizer upstream of the vaporizer. Both the experimental and analytical results show that within the present parameter range, the spray Sauter Mean Diameter and drop size distribution parameter increase with downstream vaporization distance. |
