VIV amplitude control improves with adjustments to axial tension and internal flow density, reducing vibrations significantly.
Results showed over 35% reduction in drift distance under specific conditions through effective mass regulation.
Using the wake oscillator model, an analytical framework assessed dynamic responses across typical current profiles.
Dynamic variations noted included vortex shedding lock-in effects, multi-frequency resonance, and different energy distribution patterns.
