Ensuring reliable estimates of service life is essential for the economic viability of non-renewable energy infrastructure. In intelligent well completions, control lines are mechanically critical components that are susceptible to flow-induced vibrations caused by highly turbulent annular cross-flow conditions. This study numerically investigates the unsteady hydrodynamic loads acting on control lines exposed to impinging turbulent jets in an annular configuration representative of smart well environments. The results show that the fluid forces are strongly localized near jet impingement regions and are dominated by broadband turbulent fluctuations, providing essential input for fluid–structure interaction analyses and improved fatigue-life prediction of well-completion systems.
