A technique has been developed whereby the three-dimensional (3-D) motion of particles in a fluid flow is automatically analyzed. A CCD (Charge Coupled Device) camera was used in conjunction with a tri-split lens and a mirror arrangement to simultaneously record stereo and orthogonal views of the particle-seeded flow field. A two-stage calibration algorithm has been implemented to determine the coefficients for each view separately. The images were digitally enhanced to aid in separating the particles from the background. Algorithms were developed to match individual particles in the stereo and orthogonal views. The positional information obtained from the stereo views was used to match the particle images in orthogonal views. A 3-D cross-correlation algorithm has been implemented to follow the particles from frame to frame and compute the velocity vectors. Experiments have been carried out to obtain the velocity profiles in a cubical test section. The results obtained from the experimental investigation were compared with numerical simulation data obtained from FLUENT and STAR-CD.Dept. of Mechanical, Automotive, and Materials Engineering.
