Particle Image Velocimetry (PIV)

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.

We offer a range of PIV solutions to meet specific research requirements. These innovative systems utilise a single camera to measure two velocity components within a plane. For more advanced requirements, we provide multiple camera systems that can measure three velocity components either within a plane or a volume. Additionally, we offer high-speed systems that are specifically designed to study vortices.

To ensure the highest quality measurement, our advanced features include uncertainty estimation, propagation, post-processing routing for vortex detections, combined PIV/LIF/Shadow measurement, and pressure computations.

Key Benefits

  • Does not disturb the flow
  • One can compare the results to what can be seen in images
  • Simultaneously probes an entire area
  • Versatile technique tailored to your needs
  • From 0 m/s to supersonic
  • From below mm² to several m²
  • With cameras offering up to 29MP even small scales can be resolved
  • Modern High-Speed cameras offer up to 25kHz @1MP resolution, cropping the sensor further increases the speed
  • For robust and fast data analysis
  • Post-processing and data analysis from vortex analysis over frequency analysis to pressure calculations
  • Easy to use imaging software platform DynamicStudio from data acquisition to data export
  • Calculate pressures from planar averaged or time-resolved velocity fields

Key Features:
