Time-Resolved PIV
Particle tracks at high seeding densities
Large Scale PIV/PTV in air
FlowMaster Time-Resolved (High-Speed) PIV systems measure velocity and acceleration fields and turbulence quantities of transient flow phenomena. Correlated velocity fields are acquired at frame rates up to 100 kHz realized with state-of-the-art high-speed CMOS cameras and high repetition rate lasers. Advanced multi-frame correlation algorithms enable a higher dynamic velocity range and spatial resolution of the velocity field. From correlated velocity data DaVis TR-PIV software extracts flow features in time and space such as:acceleration fieldstime tracks of vorticesspace-time correlationspower spectratime dependence of POD-modesfluid element tracking
LaVision has long-time experience in determining the most appropriate and cost-effective TR-PIV solution for a wide variety of flow applications. For tailoring the best FlowMaster TR-PIV system we carefully take into account the right choice of seeding particle and, depending on its size, the necessary illumination level and the system’s optimal repetition rate for successful time-resolved PIV measurements.
