Effect of Manufacturing Inaccuracies on the Wake Past Asymmetric Airfoil by PIV

The effect of manufacturing geometry deviations on the flow past a NACA 64(3)-618 asymmetric airfoil is studied. This airfoil is 3D printed according to the coordinates from a public database. An optical high-precision 3D scanner, GOM Atos, measures the difference from the idealized...

Experimental investigation of the unsteady stator/rotor wake characteristics downstream of an axial air turbine

A feasibility study of velocity field measurements using the Particle Image Velocimetry (PIV) method in an axial air turbine model is presented. The wakes past the blades of the rotor wheel were observed using the PIV technique. Data acquisition was synchronized with the shaft ...

Secondary flow of second kind in a short channel observed by PIV

By using the Stereo Particle Image Velocimetry (PIV) technique we observe the secondary flow of second kind in a corner of a channel of square cross-section. The boundary layer thickness is much lower than the channel size. Therefore, the flow is still developing, not filling&...

Individual Vortex Searching Algorithm

The turbulent flows consist of vortices and other coherent structures, whose motion is such highly ordered, that it is usually considered to be random. We try to bring light into this problem by using the ideas coming from research of superfluid flows, where the turbulence...
