摘要/Abstract

摘要： 为获得航空煤油在超声速气流中喷射雾化后粒径二维分布信息，设计了基于PLIF/Mie双光谱成像法的测量系统。在PLIF/Mie煤油超雾化粒径测量方法基础上，实现了SMD计算公式系数的标定和煤油超声速射流破碎和雾化的SMD二维在线测量，取得射流雾化场SMD径向分布、穿透深度、展向输运宽度等关键参数。结果表明:射流分两个阶段，前期突变阶段和稳定阶段，在初始射流压强为1.0MPa，来流初始压强为0.5MPa，喷孔直径1mm，喷射角度为90°的工况下，稳定阶段煤油喷雾SMD稳定在10μm左右，射流径向SMD由内向外由小变大，整体展向宽度范围比穿透深度稍大，在各截面位置变化趋势一致。

Abstract: In order to obtain the two-dimensional distribution information of the particle size distribution in the supersonic flow of aviation kerosene， a measurement system based on PLIF/Mie dual spectrum imaging was designed. On the basis of the measurement method of PLIF/Mie kerosene atomization particle size， the calibration of SMD calculation formula coefficients of SMD two-dimensional measurement of kerosene supersonic jet breakup and atomization has been realized， and the key parameters such as radial distribution of SMD， penetration depth and spanwise transport width have been obtained. Results show that the jet can be divided into two stages--the unstable stage and the stable stage. When the initial jet pressure is 1.0MPa， the initial flow pressure is 0.5MPa， the nozzle diameter is 1mm， and the injection angle is 90°， the kerosene spray SMD stabilized at around 10μm in the stable stage. The radial SMD of jet is changed from small to large from inside to outside. The overall spanwise transport width range is greater than the penetration depth， but the trend of change in the position of each section is the same.
