文摘
- •
We presented FSI approach with hybrid DES model for simulations of VIV at subcritical Reynolds number.
- •
The numerical model was validated against experimental data for fixed cylinder with excellent agreement.
- •
The hybrid DES model showed superiority in prediction compared to traditional RANS.
- •
Hybrid DES model was able to capture various wake flow patterns observed in VIV.
- •
The proposed FSI approach provided good prediction of VIV responses for cylinders with one and two DOF.
