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。介绍了PLIF/Mie双光谱测量原理,设计了测量实验平台,包括超声速风洞、煤油喷射系统、光路、成像系统和时序控制单元等。实验表明,该测量系统能应用于超声速雾化场的粒径二维分布测量研究。In order to obtain the drop - size oi the atomization of kerosene in a supersonic air- stream, a measurement system is designed based on PLIF/Mie scatter light imaging. A measure- ment principle is introduced. An experiment plat- form is designed comprising a supersonic wind tun- nel, a kerosene injection system, an optical sys- tem, an imaging device, and a timing controller. The results show that the measurement system can be applied to drop - sizing in two - dimensional in supersonic atomization field.
