Particle Image Velocimetry (PIV)

von Karman vortex with DynamicStudio

Particle Image Velocimetry (PIV) is a non-intrusive laser optical measurement technique for research and diagnostics into flow, turbulence, microfluidics, spray atomization, and combustion processes.

Dantec Dynamics offers a range of PIV solutions to suit a variety of research needs. Basic systems utilize a single camera to measure two velocity components in a plane. More advanced systems utilize multiple cameras to measure three velocity components either in a plane or in a volume.

High speed systems are available to study vortices. Furthermore, advanced features like uncertainty estimation and propagation that tell about the measurement quality, advanced post-processing routing for vortex detections, combined PIV / LIF / Shadow measurement, and pressure computations help to get most out of your data.

PIV Solutions

 

Planar PIV

Planar PIV techniques measure two velocity components in a plane (2D2C) and utilize a single camera
 

Volumetric Velocimetry

Volumetric Velocimetry systems capture all three velocity components in three dimensions (3D3C)
 

MicroPIV

MicroPIV systems provide two velocity components in a plane (2D2C) in microchannels, lab-on-a-chip and other microfluidic devices
