- •
Simulates the flow around three cylinders using the FVM with unstructured mesh.
- •
The biased flow is monostable, not bistable at low Re.
- •
The biased flow disappears at different spacing ratio for different Re.
- •
The characteristics of the interaction forces are dominated by pressure distribution.
- •
The influence mechanism of the fluctuating forces is related to spacing ratio.
