为了分析气液针栓喷注单元雾化特性和雾化机制,采用背光成像技术和相位多普勒(PDA)系统进行试验研究,获得了雾化模式、体积流量分布、索泰尔平均直径(SMD)分布和速度场随节流水平的变化规律。结果表明:气液针栓喷注单元雾场形态为扇形雾场,雾化模式为剪切破碎。体积流量沿径向呈单峰形分布,随着节流水平降低,雾场外缘向中心收缩。SMD沿径向呈现递增规律,雾化最好的区域分布在雾场中心和两侧。SMD随节流水平增加而增大。当动量比不变时,节流水平对SMD的分布范围影响很小。针栓头部下方的中心回流区轴向尺寸随着节流水平降低而减小。
In order to analyze the spray characteristics and spray mechanism of gas⁃liquid pintle injector unit,the effects of throttling level on spray pattern,volume flow rate distribution,Sauter mean diameter (SMD) distribution and the velocity field were obtained by using backing⁃lighting photography technique and phase Doppler anemometry (PDA) system for the spray characteristics of gas⁃liquid pintle injector unit.The results showed that the spray of gas⁃liquid pintle injector was a fan⁃shaped form and the spray pattern was presented by shearing breaking.The volume flow rate presented a single peak distribution along the radial direction.With the decrease of throttling level,the edge of spray field shrank to the center.The SMD increased along the radial direction,and the best spay area was distributed in the center and both sides of the spay field.The value of SMD increased with the increasing throttling level.When the momentum ratio was constant,the throttling level had little influence on the variation range of SMD.The axial length of the backflow area below the pintle head decreased with the decreasing throttling level.
