Experimental investigation on the flow-induced vibration of a free-hanging flexible riser by internal unstable hydrodynamic slug flow
Hongjun Zhu,Yue Gao,Honglei Zhao +2 more
TL;DR: In this article, an in-plane vibration is created by the internal slug flow, and the responses along two directions in the plane are interdependent to each other in the considered gas-liquid ratio (the ratio of air flow rate to water flow rate).
Journal ArticleDOI
Numerical analysis of mitigating elbow erosion with a rib
Hongjun Zhu,Shuai Li +1 more
TL;DR: In this article, a trapezoidal rib installed at different positions on the extrados of a 90° elbow is investigated numerically with the intent of mitigating the erosion, and a reduction of elbow erosion peak up to 31.4% can be achieved by placing the rib at θ ǫ = 25°.
Journal ArticleDOI
Piezoelectric energy harvesting from vortex-induced vibration of a circular cylinder: Effect of Reynolds number
Mingjie Zhang,Chengyun Zhang,Abdessattar Abdelkefi,Haiyan Yu,Oleg Gaidai,Xiang Qin,Hongjun Zhu,Junlei Wang +7 more
TL;DR: In this paper, the effects of the Reynolds number on the piezoelectric energy harvesting from vortex-induced vibrations (VIV) of a circular cylinder are investigated. And the results also show that the performance of a VIV-based piezolectric EH harvester is more sensitive to the Reynolds numbers for a case with low mechanical damping ratio.
Journal ArticleDOI
Underwater spreading and surface drifting of oil spilled from a submarine pipeline under the combined action of wave and current
TL;DR: In this article, a numerical investigation on the underwater spread and surface drift of oil spilled from a submarine pipeline under the combined action of wave and current was carried out to examine the effects of physical ocean environment, leaking flux and spilled oil density and viscosity.
Journal ArticleDOI
Numerical simulation of flow around a submarine pipe with a spoiler and current-induced scour beneath the pipe
TL;DR: In this article, a numerical study is performed on the flow field around a submarine pipe equipped with a spoiler and the variation of seabed surface caused by current-induced scouring beneath the pipe.
