Discussion

This analysis demonstrates vortex-induced vibration patterns in flexible cylinders, suggesting advantages over traditional CFD methods.

Simulations show distinct vortex-induced vibrational responses in inclined and curved flexible cylinders, indicating complex interaction with flow.
The proposed method achieves accuracy without empirical coefficients, validating against benchmark experiments on inclined cylinders and catenary risers.
Structural modeling employs a tensioned Bernoulli–Euler beam, resolving time-domain dynamics and flow effects effectively.
Notable findings include modal group switching behavior and energy transfer patterns that enhance understanding of complex offshore structures.

Xia et al. (2025) studied this question.
