| Abstract: | In order to realize the PIV measurement in hyper/supersonic flow,the PIV seeding technique was developed in hypersonic innovation technique laboratory of SJTU.In the study,a set of PIV tracer particles disperser system was exploited and the particles filling method using vacuum suction was designed and an effective process sequence was selected.By comparing the effects of different injection pressures and fluxes of seeding generator,an effective test program was obtained. |
