System and Method for Three Dimensional Particle Imaging Velocimetry and Particle Tracking Velocimetry

A particle velocimetry system, comprising:

• an input for receiving imaging data from a plurality of two-dimensional image sensors adapted for generating two-dimensional flow images of a three-dimensional particle laden fluid flow;
• a memory storing a particle velocimetry algorithm for tracking the movement of particles in the particle laden fluid flow based on the flow images received from the plurality of image sensors;
• and
• a processor programmed to execute the particle velocimetry algorithm to track the movement of particles in the particle laden fluid flow based on the flow images received from the image sensors, by:
• executing a particle reconstruction routine to determine three-dimensional positions of particles in the particle laden fluid flow from the flow images received from the image sensors;
• generating a three-dimensional particle distribution from the three-dimensional position data determined by the particle reconstruction routine;
• and
• executing a recursive loop for iteratively executing the particle reconstruction routine and the generation of three-dimensional particle distributions, with the recursive iteration of the particle reconstruction routine being executed with the use of particle property data obtained from the prior executed iteration of the particle reconstruction routine and/or the generation of three-dimensional particle distributions.
