In actual oil exploration process, vortex-induced vibration (VIV) is the main source of structural fatigue damage of the risers. In this paper, VIV of a flexible cylinder experiencing combined uniform and oscil
(2018c) experimentally investigated the FIV characteristics of two side-by-side flexible cylinders inclined at 45° with a center-to-center spacing of 3.0D in a towing tank. In their experiments, three cases, including two side-by-side inclined smooth cylinders, only one of smooth cylinder ...
I noticed an author derived a new definition of added mass in a relative frame of reference moving the cylinder (ekonstantinidis 2013). I encountered a problem from Eq2 to Eq3, as follows: Why the volume integral term, I In Eq.2 (ekonstantinidis 2013, from, Brennen 1982), is assumed co...

Numerical investigation of vortex-induced vibration (VIV) of a circular cylinder in oscillatory flow. In: Proceedings of the 30th International Conference on Ocean, Offshore and Arctic Engineering, OMAE. June 19-24, 2011, Rotterdam, The Netherlands.Zhao, M.; Cheng, L., and An, H.W., 2012...
The quasi-three-dimensional method was employed to simulate the flow past a long stationary cylinder in shear flow. Cellular shedding was observed in its wake. The free transverse flexible vibrations of the same body exhibited significant spanwise correlation over a large length of the body despite...

By analyzing the bending moment near the touchdown point, it is found that under the combination of the ocean current and oscillatory flow the vessel motion may decrease the VIV response, while increase the excited frequencies. In addition, the decreasing rate of the VIV under vessel surge is ...
