Abstract

Fluid Structure Interaction (FSI) simulation has been used in modelling turbulent flow induced vibration of a curved tube with fixed supports. The vibration behaviour is studied through modal analysis. It is subsequently simulated to study the structural response induced by turbulent flow using LES. LES modelling has been reasonably used for the instantaneous pressure fluctuations it can generate on the tube wall. The high response can be caused by resonance effect between natural frequency and flow induced oscillation frequency. A flow induced response test has been performed. The comparison indicates the simulated response is 18.1% higher than the measured response.
