Particle Image Velocimetry System
Particle Image Velocimetry (PIV) is a flow measurement and analysis technique for obtaining velocity vectors and streamlines by image analysis in a two-dimensional flow field. A two-dimensional flow field is visualized by using a laser light sheet to illuminate micro particles injected into the flow. IIC's PIV system makes it possible to understand the phenomena of various types of flow.
Components of the PIV system
| Double-pulsed YAG laser | PIV illumination source |
| Synchronizer | Controller for synchronizing all of the PIV system components |
| Image capture device (CCD camera) | A high-resolution digital CCD camera captures two images by means of a frame straddle link in small time intervals |
| Software | For setting flow field parameters and analyzing PIV images |
Application examples
- Air flow around a bridge model in a wind tunnel test
- Air flow around a building model in a wind tunnel test
- Inlet gas flow of a turbocharger
- Confluence of water ways
PIV faciliates easy measurement and analysis of flow fields that are difficult to measure with conventional methods. IIC's PIV system will assist engineers in the field of flow dynamics.
