1 TODO summary table– new setup, results, and limits

Authors, year	Methods	flow regime	new in setup	new in results	limits	DOF
Guofei	Num. 3D LES	subcritidal	3D LES			1
Munir, 2018, OE	Num. 2D, RANS	subcritical	cosine wave	wave (kc) effects		2
* Barbosa, 2017, JFS	Exp.	subcritical	more gap ratio, extend wake oscilator model	detailed g/d on A*, f*; extend wake oscilator model including wall effect	no mechanism explanation, flow field parameters, TI, vorticity, streamline contour	2
*Hsieh, 2016	Exp.	subcritical	high resolution PIV, Accurate measurements at the viscous sublayer	vorticity evolution in one period, shear stress along streamwise	only G/D=0.8
*Wang, 2013, JFS	Exp.	subcritical	high resolution PIV, m*=1 (floating)	St vs e/D, non-linearity (multi-harmonics) in drag coefficient (Fig.6),	no lower branch data due to exp. limit; 2. virticity contour, no upstream BL, only wake flow pattern 3. only 2 velocities at different G/D	1
*Yang,2009	Exp.	subcritical	early Exp. viv near plane	results of A* near a plane	no mechamism explanation for amp. and fre. resonse under different G/D
Sumer et al. 1994		subcritical
chen 2019 JFS	Num.	laminar		effects of BL on the VIV, impacts of G/D, and δ/D	only initial and lower branches
Chern, 2018, JoM	Num.	laminar	direct-forcing IB method	effect of e/d on lock-in region, skin friction on the plane	no physics explain
chung, 2016	Num.	laminar	moving wall, examine G/D effects only, excluding effects of the BL by moving the plane boundary	G/D ↑, A* ↓, lock-in region ↑,Urmax ↑

what did munir did? how? results? limits?

• table is inspired by 8.3.2 sumer, 1997
• ν of water: 1.002e-3
• govening/influencing parameters
• flow regime is based on table 1-1, zdravkovich, 1997
• degree of freedom

ref: table 1-1, zdravkovich, 1997

table 10.1 sumer,1997{B}

• where, B means book

Barbosa 2017 vs yang, 2009 what is new in barbosa's research?

• add more gap-ratio cases
• extend wake oscilator model including plane boundary effect
