| dc.description.abstract | This study concerns with the development of a simple three-dimensional technique to determine the velocity of fluid by tracing the motion of seeded particles in a flow in three-dimensions. A correction for light refraction at water-air boundary plane is applied. This technique is an extension of the two-dimensional Pulsed Laser Velocimetry (PLV) to three-dimensions. With this new scheme, one will be able to analyze non-planar and turbulent flows. To validate the scheme, firstly the algorithm will be tested with synthetic data, and secondly a three-dimensional experimental study will be performed. Calibration is necessary in order to calculate the camera parameters that are needed in the algorithm. Which with the followed by a complete analysis of data obtained from a three-dimensional experiment. Vector velocity field, utilizing a three-dimensional cross correlation technique, will be mapped. This method has been proposed in order to provide an easier experiment and calibration than the methods used previously. Indeed, it is a combination of two different techniques. The Yamainoto's scheme is a complex experimental set up with three cameras located on a sphere but which requires easy equations for the calibration. But the Nishino's technique has a simpler set up, with no requirement for the cameras positions, but it involves complex equations concerning the determination of cameras parameters To summarize, this study demonstrates the set up, data acquisition, calibration, coordinate transforms, and tracking of experimental data in three-dimensions. | en |
