Achievement: High spatiotemporal resolution two-phase flow particle image velocimetry (PIV) system

Achievement Owner: Beijing Jiangyi Technology Co., Ltd.

Introduction: The high spatiotemporal resolution two-phase flow particle image velocimetry (PIV) system has completely independent intellectual property rights, and has realized the complete localization of a complete set of hardware equipment and software. The system adopts the most cutting-edge algorithm results of particle image velocimetry technology, modularly integrates the most advanced products of high-frequency pulsed lasers and high-speed cameras. It can carry out high-temporal-spatial-resolution and three-dimensional flow fields observations for two-phase flows. The maximum time resolution of the system can reach 1μs. The sampling frequency of the flow field is increased from the 10Hz level of the standard PIV products to the 106Hz level, and the maximum spatial resolution is increased from the 1mm level of the standard PIV products to the 10m level, and the maximum measurable speed can reach more than 5000m/s (such as underwater shock wave).
