Dantec Dynamics - 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.
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.
Advanced Analysis and Data Visualization
- Our imaging software DynamicStudio comes with advanced analysis and visualization capabilities.
- You can create quality 2D and 3D graphics and animations from your measured data.
- For traceability and comfort, no exporting and re-importing of data is necessary; all data is retained in DynamicStudio.
- Advanced analysis features and Post Processing routines in DynamicStudio offer lots of features that simplify the life of fluid mechanic experimentalists.
- Adaptive PIV for easy, precise and fast planar PIV data analysis
- Uncertainty estimation and propagation compute the uncertainty of each vector and can propagate it into velocity derivatives
- Analysis sequences to build batch processing libraries
- Pressure from PIV Add-on derives pressures from velocity fields
- Easy visualization tools
- Dynamic Masking Add-on to mask out moving objects
