The technique is established in the laboratory since 2001. Currently, two PIV systems are available in the laboratory, from Dantec and LaVision. A cooperation with leading suppliers of the PIV software is established (Dantec, LaVision and the Institute of Thermophysics).
The equipment and software include a high-speed stereo-PIV system, a tomographic-PIV system, a long-distance micro-PIV equipment and endoscopic micro-PIV, see Figs. 4.17-4.18. Results obtained in the laboratory are published in recognized journals and conferences. Correspondingly, results from different PIV techniques are published in Hartono et al. (2014), Niebles et al. (2016), Minelli (2017), Zhao et al. (2016), see Figs. 4.19-4.20.
