Three-Dimensional Particle Tracking Velocimetry With Laser-Light Sheet Scannings

Abstract: This paper describes three-dimensional particle tracking velocimetry (3D PTV), which enables us to obtain remarkably larger number of velocity vectors than previous techniques. Instead of the usual stereoscopic image recordings, the present 3D PTV visualizes an entire three-dimensional flow with the scanning laser-light sheets generated from a pair of optical scanners and the images are taken by a high-speed video system synchronized with the scannings. The digital image analyses to derive velocity components … Show more

“…While not yet as mature as their 2D counterparts, 3D PTV techniques have been documented in a number of recent works (Maas et al 1993;Ushijima and Tanaka 1996;Virant and Dracos 1997;Kieft et al 2002). The stereoscopic PTV technique implemented in the present work builds on earlier works by Spinewine et al (2003) and Douxchamps et al (2005).…”

“…Kasagi's group has applied the technique to unsteady laminar Couette flow, isotropic decaying turbulence, fully-developed turbulent channel flow, an axisymmetric free jet and other interesting basic flows. Typical volumes examined for three-dimensional PTV have been 4 x 4 x 4 cm 3 , 10 x 10 x 1.5 cm 3 [Papantoniou and Dracos, 1990], 8 x 8 x 8 cm 3 [Kasagi and Matsunaga, 1995] and 6 x 6 x 6 cm 3 [Ushijima and Tanaka, 1996], i.e., small compared to the volume treated in the present study. The possibility of tracking individual particles through larger volumes was demonstrated by Lowe et al [1993].…”

“…For the 3D vortex structures in the CTCs and vortical plume regimes, this study provides such details by developing a simple visualization technique of the vortex structures based on velocity field data obtained using scanning planar PIV, which is conventional technique with scanning illumination by movable laser sheet (e.g. Ushijima and Tanaka 1996), considering sufficiently slow advection of the columnar vortices, and post processing.…”
