Time-Resolved PIV measurement in a turbulent flame

Time-Resolved PIV measurement of wake flow behind a car. Courtesy of PSA, France Combining our know-how of fast, accurate synchronization and rapid digital image capture, we offer complete measurement solutions for PIV applications with all the required elements integrated into turnkey systems Particle Image Velocimetry (PIV) PIV is an intuitive measurement technique for measuring two or three components of velocity in a variety of flows. The application of PIV in research and industry is widespread, due to its ease of use and accurate data representation. As easy and intuitive as PIV is,...

The Principle of PIV Double Pulsed Laser Cylindrical Lens ∆t Data Visualization Velocity Field ∆t Flow Frame 2 Camera & Optics Frame 1 Particle Images Correlation An overview showing the principle of Dantec Dynamics' 2D PIV systems Two consecutive laser pulses illuminate a slice or volume of a flow field with particles suspended in the flow. The scattered light from the particles is recorded in two consecutive images on one or several digital cameras. Taking into account the magnification of the optical setup, the absolute velocity field can be derived. The velocities calculated from an...
