In previous articles we have proved that it was possible to modify the hydrodynamic parameters of high speed jets of diesel oil with electrical processes. The modifications were observed on the velocity, the size of the droplets and on their distribution in the space with a PDPA system. From these experiments we had concluded that the electrification of the(More)
The three-dimensional flow that develops around a finite flapping wing is investigated using a tomographic scanning PIV technique. The acquisition and correlation processes employed to achieve such measurements have been carefully validated. Issues regarding the relevant timescales of the flow and the spanwise spaceresolution are addressed. Results obtained(More)
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(More)
