超声速雾化粒径二维分布测量系统设计

摘要

In order to obtain the drop size of 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.%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。
