The flow of dense fluids within thin-walled piping systems may lead to significant levels of Flow-Induced Vibration, mainly in the vicinities of singularities such as obstacles inserted into the flow, sudden changes of cross-sectional area or flow direction. This study focuses on the analysis and reduced-order modelling of the vibrational source associated with the turbulent flow of liquids through a 90° elbow.A mixed experimental-computational approach is undertaken. A closed water loop containing a transparent elbow was designed in order to allow for fluid velocity measurements inside the singularity. To this purpose, planar and stereoscopic Particle Image Velocimetry (PIV) were employed. Wall pressure fluctuations and structural vibratio...
