| Abstract: | Particle image velocimetry (PIV) is an important method for flow field measurement. This method is based on seeding flow tracers in a flow field and extracting quantitative information about the velocity components by measuring their simultaneous displacements over a short interval of time. Some selected state of the art applications in 3-D measurement and alternative signal processing methods are reviewed. The trends for future developments of PIV are discussed in the paper. |
