Tomographic PTV (4D-PTV)

DynamicStudio allows users to make high seeding density measurements in a variety of applications and perform Time Resolved 3D Lagrangian particle tracking.

The DynamicStudio Software Platform offers Tomographic PTV as a fast and precise method for tracking individual particles in a 3D measurement volume. Using powerful reconstruction algorithms, a 3D digital image is created from three or four, 2 dimensional camera images. The 3D position of each particle can then be plotted through the measurement volume and via 3D Lagrangian Particle Tracking.

When the measurement system can acquire images fast enough to follow particles for many timesteps as they progress through the measurement volume, Time Resolved 3D Lagrangian Particle Tracking is possible (sometimes referred to as 4D Lagrangian Particle Tracking).

Dantec’s Tomographic PTV code has been tested on synthetically generated data and a variety of experimental data to illustrate the ability to track particles in high seeding density configurations. For water applications, a variety of seeding particles can be used from 10um-100um spheres, and Time Resolved Volumetric PTV measurements can be illuminated by lasers or high power LEDs.

In air, Tomographic PTV can be performed with 1-10um oil droplets in combination with a laser for illumination. Alternatively, the physical size of the 3D measurement can be increased using 500um sized Helium Filled Soap Bubbles from the Dantec Helium Filled Soap Bubble Generator.  In this case lasers or LEDs can be used for illumination, depending on the flow velocity.

In all cases the Tomographic PTV algorithms output data for densely seeded flows as Time Resolved 3D Lagrangian Particle Tracks. Data can be visualized as particle tracks or converted to a regular grid for further interrogation and calculations.
