PIV measurements of a microchannel flow
A particle image velocimetry (PIV) system has been developed to measure velocity fields with order 1-lm spatial resolution. The technique uses 200 nm diameter flow-tracing particles, a pulsed Nd: YAG laser, an inverted epi-fluorescent microscope, and a cooled interline-transfer CCD camera to record high-resolution particle-image fields. The spatial resolution of the PIV technique is limited pri...
متن کاملPiv of a Precessing Cylinder Flow at Large Tilt Angles
Planar particle image velocimetry measurements of the flow in a precessing cylinder are presented for nutation angles of up to 15◦. For a case of a moderate Reynolds number, we observe a rapid transition to a disordered state with a brief appearance of structures of high azimuthal wave numbers. Similarity to observations reported in previous experiments and numerical simulations at much lower t...
متن کاملSteady Vortex Breakdown in Swirling Flow Inside a Closed Container: Numerical Simulations, PIV and LDV Measurements
Numerical simulations and measurements using PIV and LDV have been carried out for steady vortex breakdown inside a closed container. The numerical solution has been employed as a benchmark to assess the capabilities and limitations of the experimental techniques in a difficult flow case involving a double breakdown in the limit of the
متن کاملDirect experimental comparison between tomo-PIV and scanning tomo-PIV: wake flow behind a half-cylinder
In this paper, a direct experimental comparison is made 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 the seeding density on the volume reconstruction fo...
