governing and influencing parameters:
- Re(flow regimes)
- G/D
- m*ξ (Govardhan & Williamson 2006)
- BL(laminar, turbulent, thickness/G)

1.1 validation
stationary cylinder no plane boundary
The velocity field of the turbulent very near wake of a circular cylinder
By:Ong, L (Ong, L); Wallace, J (Wallace, J)
1.2 khalak and Williamson,1997, JFS
NEW input variables: Very low m*ξ Q?
- what is the dominant response frequency during excitation
- lock-in region
- A* vs. Ur
exp. U* = U/fn D, where fn is the natural frequency of the structure in water
2 setups
- all setups are the same as Khalak and Williamson 1997 except add a plane boundary
- Re(1e3, 1e4)
vibration-system
- low M* (<6)
3 new contribution from guo fei
- flow field properties
- higher Re, others work mostly on laminar (# not great new, lots of work on subcritical flow regime)
- 3D rather than 2D
- non-linearity
- wider G/D

intermittent {adj}
occurring at irregular intervals; not continuous or steady. "intermittent rain"
