Particle Image Velocimetry (PIV)
Measurement principles:
Particle Image Velocimetry (PIV) is a whole‐flow‐field technique providing instantaneous velocity vector measurements in a cross‐section of a flow. Two velocity components are measured. The use of modern digital cameras and dedicated computing hardware, results in real‐time velocity maps.
Advantages
- The technique is non‐intrusive and measures the velocities of micron‐sized particles
- Velocity range from zero to supersonic
- Instantaneous velocity vector maps in a cross‐section of the flow
- Sequences of velocity vector maps or statistics are available
