In the design of Japan Sodium-cooled Fast Reactor (JSFR), the flow-induced vibration (FIV) arising from the piping geometry and operating condition may occur in the short-elbow pipe. In this study, water experiments using two types of 1/8 scaled elbows with different curvature ratio, r/D = 1.0 and 1.5, were conducted in order to investigate the mechanism of flow fluctuation due to the elbow curvature. The measurements of the velocity fields and pressure fluctuation revealed that the periodic pressure fluctuation of St = 0.56 occurred near the separation region which was formed constantly on the wall of inside.
