Abstract
High spatial resolution time-series PIV system, time resolution of which potentially ranges from several hundreds Hz to several tens kHz, has been developed using two high-repetition-rate Nd : YAG lasers for industrial processing and a high-speed CMOS camera. The developed system was applied to a turbulent jet and fluid flow maps with 26.7kHz time-resolution were obtained. In addition, various time-resolution measurements up to 16kHz were conducted to estimate the performance of the developed high spatial resolution time-series PIV system. From the time-series PIV measurement, dynamics of the turbulent structure can be visualized clearly.
