Direct experimental comparison between tomo-PIV and scanning tomo-PIV: Wake flow behind a half-cylinder

In this paper, a direct experimental comparison ismade between scanning and tomo-PIV, on an unsteady wake flow behind a half-cylinder. Several seeding densities are used in order to demonstrate the capacities and limitations of both techniques. For the scanning technique, the effect of particles elongation is investigated and the influence of...

Assessment of the statistical relevance of TR-PIV datasets

The increasing interest for high repetition rate global optical measurement techniques such as Time-Resolved Particle Image Velocimetry (TR-PIV) raises a number of questions concerning their ability to provide relevant statistical and spectral quantities. In an effort to address this issue, complementary TR-PIV and Laser Doppler Velocimetry (LDV...
