Aerodynamic Testing: PIV in Wind Tunnels

Aerodynamic testing is often the key to success in car racing and also for transport vehicles to achieve the best fuel economy. Multidimensional and often time-resolved Particle Image Velocimetry (PIV) measurements are applied in wind tunnels to balance aerodynamic shape with automotive styling and to reduce wind noise (aeroacoustics).
LaVision’s FlowMaster PIV systems provide real-time and accurate flow field measurements, support remote measurement control including flow field scanning in all directions and data synchronization with other wind tunnel test parameters. This guarantees short development times avoiding costly wind tunnel down-times.
