MINI PIV system mainly includes MINI PIV system and MINI PIV teaching system. Brief introduction: Particle Image Velocimetry, a two-dimensional Particle Image Velocimetry system with independent intellectual property rights for commercial use in China, is a system made up of digital cameras, lasers and professional MicroVec PIV Image analysis software. MicroVec specialized particle image analysis software processing, various complex fluid dynamics velocity field parameters can be real-time display and analysis. Support the measurement of two-dimensional velocity field (2 Component) information in two-dimensional section (2 Dimensional). The measuring speed range is 0-3m/s, the measuring area scale is 1mm-200mm, and the measuring medium can be transparent fluids such as water and air. Introduction to MINI PIV teaching system: In order to help researchers deepen their understanding of concepts related to convection mechanics and PIV technology theory, Beijing cubitiandi technology introduced the MicroVecMini V5.1 teaching system in 2018, which is simple to operate and easy to carry. MINI PIV system and teaching system features: 1. Commercial MiniPIV with independent intellectual property rights; 2. Built-in world-class and high-precision third-generation PIV algorithm module; 3. Intuitive high-tech flow field visualization equipment; 4. Digital images are stored in the computer memory or hard disk at a high speed (continuous hard disk image acquisition with a height of 100fps can be realized, and the acquisition rate of the teaching system can reach 800fps); 5. Real-time flow field results show that it is easy to understand and grasp the concept of convection mechanics; 6. Flexible and reliable software control of laser, digital camera and external synchronization signal in two-dimensional test, maintenance-free hardware design. MINI PIV system and teaching system application: 1. Simple and easy-to-operate particle image velocity measurement system; 2. Simple integrated optical design; 3. Powerful post-processing software support; 4. Water tunnel/flume fluid test; 5. Water jet test; 6. Study on micro-scale deformation; 7. Particle/particle analysis.
