Abstract: Particle Imaging Velocimetry (PIV) offers many advantages for
studies of fluid flows. Lots of PIV techniques have been developed and applied
to various flow fields. However, there are no standard tools for evaluation of
the PIV system effectiveness and accuracy. To popularize the PIV for practical
use, the PIV system should have some standard. The Visualization Society of
Japan (VSJ) started a project for PIV standardization and popularization in
1996 (PIV-STD Project). The PIV has two processes, i.e., the image capture with
visualization and image analysis. In order to evaluate the image analysis
system for the PIV, standard images were proposed. Using the images, an
evaluation of the effectiveness and accuracy for the PIV system will be carried
out. The developed PIV standard images are distributed using the Internet,
(http://www.vsj.or.jp/piv). The standard images include the two-dimensional and
transient three-dimensional images. The correct velocity vectors and correct
particle location in three-dimensional field are also provided to evaluate the
effectiveness of the target flow field.
