Few works use the fully three-dimensional computational fluid dynamic method to simulate the flow fields around the marine pipes with large aspect ratios due to the huge computation cost. In the present work, an operator-splitting method is used to e

While it is known that rigid splitter plates play significant roles in flow control, the exact roles of them in flow-induced vibration (FIV) have not been systematically investigated. This has motivated the present work to experimentally investigate

The galloping oscillation of a circular cylinder combined with different fairing devices is numerically studied. The fairing devices are integrated with a circular cylinder that is supported by a spring and a damper. An unsteady Reynolds-averaged Nav

In this paper, double tail splitter plates (DTSPs) have been investigated to suppress the flow-induced vibrations (FIVs) of both an elastically mounted single circular cylinder and one-fixed-one-free tandem cylinders in a wind tunnel at Re = 4000-480

A flexible fishtail-like fairing, adopted as a flow-induced vibration(FIV) suppressor, was studied in a wind tunnel at Reynolds number 4000–42000. It is shown the vortex induced vibration can be practically eliminated by using FTF. The effect of th

Fairings have been used to suppress the vortex-induced vibrations(VIV) of deep water cylinders in the offshore and marine engineering applications. When properly functioning, they can reduce both the cylinder oscillation amplitude in the cross-flow d

Galloping oscillation has been observed in the practical applications of the fairing devices on offshore oil and gas risers. The ability of the riser movement prediction codes to predict the galloping oscillation is important since major structure fa

Buoyancy modules are essential parts in the offshore oil and gas drilling and production practices. They provide weight compensation for the riser and help avoid excessive top tension exerted by the floating platform. However, the deployment of buoya
