The critical damping factor for intelligent control lines was estimated using FSI simulations of an elastic cylinder subjected to cross-flow. Detached Delayed Eddy Simulation (DDES) was employed to model the turbulent flow, while the cylinder's displacement was calculated by assuming linear elastic material behavior. Vibration frequencies, displacement amplitudes, and forces were determined through finite element analysis (FEA) based on the conservation equations. The most significant vibration frequency was extracted from the lift force's Power Spectrum Density (PSD). The critical damping factor was then optimized by adjusting it until the ratio of displacement to lift obtained from FSI matched the value derived from FEA.
