An increasing number of subsea developments today concern gas fields characterized by high flow velocities, which is the governing parameter for the occurrence of Flow-Induced Vibration. FIV can impose restrictions on the allowed maximum flow rates and severely limit an installations production capabilities. In this paper single- and multi-phase CFD U-RANS simulations of the flow in a sharp ID bend at moderately high Reynolds number are presented. The capability of the two-equation SST turbulence model to resolve the flow induced pressure loading on the pipe walls is addressed. It is found that for single-phase flow, the SST model is able to correctly predict the frequency and location of the wall pressure fluctuations but neither their amplitude nor the associated large-scale unsteady flow features. This work is part of a project aiming at developing a methodology for the prevention of FTV-related issues in subsea production systems.
