摘要
双毛细管静电雾化技术可增大燃油雾流场中的静电作用力,从而细化燃油雾化液滴粒径,可提高燃料液滴的雾化质量。通过高速摄影仪器对航空煤油的双毛细管静电雾化的雾化液滴荷电破碎特性、液滴的分离频率以及航空煤油的雾化液滴模式进行了实验研究,分析了航空煤油流量与电压对航空煤油在双毛细管端口的雾化模式和雾化特性的影响。结果表明,液桥长度随电压的增高而增长,粒径随电压增高而减小。同电压下,流量越大航空煤油下落频率越高,且下落频率随电压变化的幅度也随之越大;航空煤油产生稳定射流的流量范围0.18~2.55 mL·min^(-1)。
The double capillary electrostatic atomization technology can increase the electrostatic force in the flow field of fuel mist,so as to refine the droplet size and improve the atomization quality of fuel droplet.A high-speed photographic instrument was used to study the atomization characteristics of aviation kerosene by double capillary electrostatic atomization.The effect of aviation kerosene liquid flow rate and voltage on the atomization mode and atomization characteristics of aviation kerosene was analyzed.The results showed that the length of liquid bridge increased with the increase of voltage,and the particle size decreased with the increase of voltage.At the same voltage,the larger the flow rate,the higher the falling frequency of aviation kerosene,and the greater the amplitude of falling frequency with voltage;the flow range of aviation kerosene stable jet was 0.18~2.55 mL·min^(-1).
