PIV Web Visualization System toward PIV visualization grid
Journal of Visualization, 2003To visualize the simulation and experimental data, the fluid dynamics scientists and engineers have to possess a powerful visualization engine with CG package in their laboratories. We developed a Problem Solving Environment (PSE) system called "PIV Web Visualization System" to solve this obstacle, using computational grid common service tool "Globus",

Direct comparison of 2D PIV and stereoscopic PIV measurements
Measurement Science and Technology, 2002A stereoscopic particle image velocimetry (PIV) measurement system based on the translation configuration was developed and applied to the flow behind a forward-swept axial-fan with five blades in a water tank. The 3D calibration procedure was employed to compensate the distortion and refraction of particle images.

Experiments in Fluids, 2000
A non-post-interrogation method of reducing subpixel errors and eliminating spurious vectors from particle image velocimetry (PIV) results is presented. Unlike methods that rely on the accuracy or similarity of neighboring vectors, errors are eliminated before correlation information is discarded using available spatial and/or temporal data.

Applications: Stereo PIV and Multiplane Stereo PIV
2018The various methods of image reconstruction and calibration as described in Sect. 8.1 were applied in the measurement of the unsteady vortex ring flow field in 1995. Figure 11.125 outlines a vortex ring generator having a simple construction with very reproducible flow characteristics.

Analysis of stereoscopic PIV measurements using synthetic PIV images
2004This paper describes the use of a synthetic image generator (SIG) for the assessment of the precision of a stereoscopic PIV system. The geometry implemented with the SIG closely matches that of an existing stereo-PIV measurement in laminar pipe flow. The calibration procedure is simulated, which demonstrates the necessity of a careful alignment between
