引言本文设计开发了一套可用于柴油机瞬态喷雾场测试的ＰＩＶ（ｐａｒｔｉｃｌｅｉｍａｇｅｖｅｌｏｃｉｍｅｔｒｙ）系统，该系统利用喷雾液滴对入射激光产生Ｍｉｅ氏散射的原理，并以此作为示踪粒子，利用照相机对喷雾场进行瞬时拍照。ＰＩＶ照片经图像处理可得到喷雾液...
Introduction This paper designs and develops a PIV (particleimagevelocimetry) system which can be used for transient spray field test of diesel engine. The system uses the principle of Mie scattering generated by the spray droplets on the incident laser and uses it as tracer particles. Field instant photo. PIV photos by image processing can be sprayed liquid ...
