Abstract:

Volumetric Three-Component Velocimetry (V3V) is a technique developed by TSI to measure the velocity fields in a volumetric domain. It is a 12- mega-pixel CCD camera with three apertures for 3D recording of images. V3V can obtain readings from a volume up to 140 × 140 × 100 mm 3 at the 7.25 Hz capture rate used in the PIV technique. The particle images are processed using a pattern search algorithm, to find the positions of the tracer particles, then particle tracking is performed to obtain the 3D velocity vectors. V3V has the capability of capturing up to 50,000 particles in a single image. This paper is a general review on the basic theory of V3V and its applications.
