Vortex Generators - Flat Plate

Managed by

Site Description: 

Particle Image Velocimetry (PIV) measurements of vortex generators (VG) on a flat plate with zero- and adverse-pressure gradients. Time-averaged velocity fields with turbulence statistics have been acquired in transverse planes in the wake of rectangular, vane-type vortex generators up to 50 device heights downstream the VG trailing edges.

Data Provider: 

Daniel Baldacchino and Carlos Ferreira (Delft University of Technology).

Data accesibility:

Instrumentation: 

Three-component, planar velocity measurements were conducted using stereo particle image velocitmetry. The setup consisted of two 16 Mpix cameras and a Nd:Yag laser. The laser sheet was aligned in lateral planes behind the VGs and the entire measurement system was traversed in the streamwise direction to acquire data in up to 10 planes, reaching as far as 50 device heights downstream the VG trailing edges.

Measurement Campaign: 

Experiments were conducted in May 2014 in the Boundary Layer Wind Tunnel at Delft University of Technology.
