Paper Abstract

This paper presents a new achievement in PIV image processing research. A new image processing software system of particle tracking velocimetry has been developed. This system is based on a series of unique image processing and patterns recognition algorithms, including image enhancement, particle identification, and particle matching. It has been evaluated with several standard PIV images constructed by The Visualization Society of Japan (VSJ). With the post processing function of the software, some other kinds of flow field characteristics could be described. Finally, this software has also been tried in practical PIV flow field measurements. This work is about the internal flow measurement of transonic compressor, conducted on the transonic compressor rig of National Air-engine Thermal Dynamic Key Laboratory, Beijing University of Aeronautics and Astronautics, China. The result of the PIV image processing was compared with that obtained with the correlation algorithm software. The comparison result has proven to be quite agreeable and even more efficient.
