Title: Development of High Spatial Resolution Measurement Technique in Two-Dimensional Particle Tracking Velocimetry
Abstract: Particle Image Velocimetry (PIV) can measure whole flow field simultaneously without disturbing the flow field. One of PIV techniques, Two Dimensional Particle Tracking Velocimetry (2-DPTV) may show us accurate results, and it can analyze the visualized digital images at high speed. On the other hand, it is difficult to achieve high spatial resolution enough. Therefore we improved particle tracking algorithms. In our old tracking algorithms, particles are tracked over tree time-steps, but in new tracking algorithms, particles are tracked over four time-steps. Even if the particle density increases, new algorithms may track each particle accurately. Our new method was compared with our old one, and in order to check the effectiveness of particle tracking algorithms, we used the standard images provided by the PIV-STD Project of the Visualization Society of Japan.
