Particle Image Velocimetry (PIV) Principle
WebPIV is a non-intrusive laser diagnostic capable of determining instantaneous two-dimensional velocity fields corresponding to the cross-sectional slices of three-dimensional flows. The operating principle of PIV stems from the following simple relation: . That is, average velocity, , is equal to the displacement, , divided by the change in time, . WebWhy High-Speed Imaging for PIV? Visible Details Using a high-speed camera in PIV, will result in accurate and detailed images for motion analysis. Phantom cameras have specially designed CMOS sensors … Webcontrol system. CIV cards have the same technical format as PIV-I cards and are technically useable in a PIV enabled access control system depending upon local policy.
