Effects of air swirl intensity on atomization and combustion performance of effervescent atomized spray were investigated under different conditions.
对不同空气旋流强度下气泡雾化喷嘴出口下游喷雾流场特性及燃烧特行进行了诊断与分析。
It was found that the stability of swirl flow decreases with swirl intensity and axial velocity raise and obviously depends on geometrical dimension of swirl sprue.
结果表明旋流强度、轴向分量速度和旋转流道的几何尺寸均会对旋流稳定性产生重要影响。
The simulation result shows that the stronger swirl intensity becomes, the stronger influences on atomization droplets has, and the more uniformly secondary air and atomization droplets mix.
模拟结果表明：二次空气的旋流强度越大，对液滴的作用越强烈，二次空气与雾化液滴的混合越充分。
The intensity of the gas backflow and axial swirl ond the dilution in the afterburner are enhanced by increasing the air-to-fuel ratio, and then the combustion efficiency is improved.
提高空燃比，可增强补燃室中燃气的回流和轴向涡流强度，加大掺混力度，从而提高燃烧效率。
