Abstract： Aiming at the characteristic of the complex flow fluid of ionic wind air accelerator，ionic wind technology was put into the aspect of air flow accelerating. Research of ionic wind technology was investigated and principle of the ion wind air accelerator was analyzed. After the analysis of particle imaging technology having effect on experimental study of ionic wind effect at home and abroad，the relationship of partied image velocimetry（PIV） technology and the fluid field of the ion wind air accelerator was established. An experimental designed method based on PIV technology was presented to test the internal flow field of ionic wind air accelerator. PIV measuring device，high voltage power supply，discharge electrode and fluid channel were designed. The PIV experimental platform was demonstrated. The purpose and meaning of the PIV experimental platform，the key and difficult point for PIV technology in ion wind air accelerator were analyzed. The controlling of tracing particle distribution，which is the key to the success of PIV experiment，was evaluated. The process of PIV experiment was demonstrated；the resources of errors from PIV experiment measurement and the experimental operations were shown. The results show that the design and research of PIV experimental platform based on ionic wind air accelerator are reasonable and rigor.
Key words： ionic wind air accelerator； partied image velocimetry（PIV）； experimental platform； fluid field characteristic
