Particle Image Velocimetry, commonly called PIV, is an optical measurement technique that provides instantaneous velocity vectors in a flow field. It is especially used to analyse the organized structures in the turbulent flows.
S2A owns a 3D stereo PIV system usable in both wind tunnels. In the Full Scale Wind Tunnel, zones like wheel housings, undercarriage, rear view mirrors or wake can be studied.
Examples of PIV results :
|Team Breizh for Eco Marathon Shell|
|Reference notchback car’s wake streamlines|
