Discussion

Numerical simulation reveals that suction positioning modulates vortex-induced vibration and airflow dynamics.

Suction configurations reduce vortex-induced vibrations, with Jet 3 achieving a 99.87% suppression.
Applying suction at Jet 5 increases the peak vibration response by 53.2%, indicating ineffective positioning.
Energy input analysis shows that suction negatively impacts flow dynamics, altering aerodynamic forces.
Optimal suction locations enhance aerodynamic performance, reducing drag and fluctuating lift forces significantly.

Li et al. (2025) studied this question.
