摘要
本文论述了使用PIV测量技术时示踪粒子的选取原则和各种示踪粒子特性比较 ,并且详细介绍了一种由作者研制的带有Laskin喷头的新式粒子添加装置 ,经过试验证明效果比较理想。此种装置产生的液态粒子 ,最特殊的地方是其内部为空心。因此在相同的体积下 ,其质量比一般的示踪粒子要轻 。
In this paper, the principle of choosing tracer particle in PIV measurement and the comparison of several tracer particles are dissertated. And a new particle generator with Laskin nozzle, which is made by the authors, is introduced in detail. The particular point of the liquid particles generated by this equipment is that they are hollow. That is they have bigger bulk than the usual particles with the same mass. So they are very suitable to the PIV measurement.
