Abstract:
The char acteristics of different PIV ( Particle Imaging Velocimetry) technologies ware gener alized in this paper. In v iew of the complexity and hig h ex pense of these systems, a new approach to obtain the 2- D velocity field based on the tw in FFT to the single spatial laser tomo graphy images is proposed and a simple system based on this method is also dev eloped. The ex perimental results show that g ood effect was achieved for the measur ing range of low velocity and the PIV wit h lower expense can be ex pected.
