Three-dimensional particle tracking velocimetry study of marine organism wake behavior

Three-dimensional particle tracking velocimetry (3D-PTV) is a flow measurement technique that tracks Lagrangian trajectories of passive tracer particles using stereoscopic imaging. The technique allows for detailed analysis of the velocities along particle trajectories in unsteady flows. The implementation and optimization of the technique is involved however, requiring precise attention to the correct methods of system setup, camera calibration, and processing. This thesis aims to develop an optimal system setup for the use of 3D-PTV for studying flow behavior in the wakes of marine organisms. Previous studies have been limited by the restrictions of other flow measurement techniques, and have been largely confined to 2D analysis. This paper describes the methods by which 3D-PTV can be optimized for this purpose, including choice of calibration target, seeding particles, and PTV software parameters. The output data is analyzed and compared with existing 2D data as a demonstration of the technique.
