- 摘要:
- 为揭示工质粘性对两股射流撞击雾化特性的影响规律，在大气开放环境下开展了不同粘度系数工质的射流撞击雾化试验。由相位多普勒粒子分析仪(PDPA)测量了撞击点下游10 mm，20 mm，30 mm与40 mm平面位置处液滴的粒径分布和速度分布等信息。试验结果表明：粘度系数增大，雾场某点处的液滴粒径有增大的趋势，运动速度有减小的趋势；雾场液滴粒径达到平衡状态时与撞击点的距离将会增加；撞击点下游某一平面的液滴平均运动速度将会减小；当粘度系数一定时，距离撞击点越远，该平面的液滴平均运动速度越小。
- Abstract:
- In order to investigate effect of working fluid viscosity on atomization characteristics of a pair of impinging jets, the atomization experiment of impinging jets of working fluid with various viscosity coefficient was carried out under the condition of open atmosphere. The information of size distribution and velocity distribution of droplets on 10 mm, 20 mm, 30 mm and 40 mm planes at downstream of impinging point was measured with PDPA. The experimental results reveal that the size of droplets at a position of atomization field has the increasing trend and the kinematic velocity has decreasing trend as viscosity coefficient increases, the distance from the impinging point grows while the size of droplets in the atomization field reaches balance, the mean velocity of droplets on a certain plane in downstream
