By means of 2D PIV (2-dimensional Particle Image Velocimetry), flow visualization experiments are carried out for a single short elbow piping which is a 1/7-scale model of the cold-leg piping of Japan Sodium-cooled Fast Reactor in order to investigate the minute flow field related especially to flow separation appearing in the intrados side of the elbow and frequency characteristics of the flow velocity fluctuation for various Reynolds number flow. A periodic motion with St of 0.5 appeared near the separation region if the Reynolds number changes.
