- •
VIV suppression on large mass-damping cylinder was presented and verified.
- •
Experiments was carried out for strakes at different geometries and cross-sections.
- •
The RMS amplitudes of "D"-type are decreased up to 85% in the CF direction.
- •
The helical strake of P/D=0.14, h/D=5 has the best suppression efficiency.
- •
Helical strakes can alter vortex shedding of bare cylinder.
