Particle Image Velocimetry (PIV)
Particle image velocimetry (PIV) enables the investigation of two-dimensional flow fields with high spatial and temporal resolution.
High-melting point ceramic oxide particles deliberately introduced into the flow are exposed by a pulsed diode laser in brief time intervals and recorded at about 40,000 frames per second using a high-speed camera.
The statistical evaluation of individual particle group positions enables the quantitative calculation of flow fields using special software.
