Particle Image Velocimetry(PIV)



・Particle Image Velocimetry (PIV) measures the two-dimensional velocity vector distribution in the flow field.
 (This will help to obtain the flow velocity distribution and turbulence intensity)

・Moreover, we can get 3D component simultaneously by Stereo-PIV.

・Regarding Stereo PIV, it requires high level of measurement skills in the calibration technique and analysis technique.
  (Imagineering will undertake a consulting service of PIV measurement.)

・For example, we can obtain both reference data and evaluation data for engine development from realistic engine
 environment.
