By means of adjusting the spiral angle and streaming area,different velocity fields,pressure fields and atomization angles are carried out to study the effect of the swirl distributor to the flow characteristics of the nozzle.

• 通过调整旋流喷嘴旋流片的螺旋升角和通流面积等结构参数,对喷嘴雾化的压力、速度场进行计算,推导了喷嘴的雾化角,从而研究旋流片对喷嘴流场特性的影响。
