B207 カラー偏心アパーチャを用いた微小空間における微粒子の3次元位置計測

抄録

In order to measure instantaneous three-dimensional velocity distributions in a small space, three-dimensional micro-PIV technique have to be developed. In this paper, the improved eccentric aperture method that could be conveniently applied to the three-dimensional PIV measurement in a small space is discussed. By introducing a color separation technique, the measurement distance can be expanded twice, and it can process dense tracer pictures. Some experimental examples are shown.
