... Abstract In engineering applications, we frequently encounter flow around circular cylinder-type geometries, such as in cooling pipes for heat exchangers, risers and pipelines in oil and gas extraction, storage silos, and buildings in civil engineering. It is widely known that unsteady flow...

... Abstract This paper investigates the hydrodynamic damping of an oscillating circular cylinder in a steady current. The standard approach for estimating the hydrodynamic loads from combined wave and current conditions on structures employs linear superposition of the loads induced by each...

... Abstract The subject of vortex-induced vibration (VIV) in a steady flow has been extensively studied throughout the past decades. There is limited experimental research presenting the influence of incoming turbulent flow on the VIV of circular cylinders which may be useful in studying real-life...

... Abstract This paper investigates the ability of physical and numerical models to simulate green water impact loads on a circular cylinder located on top of a fixed box. A focused wave group was used to overtop the box and generate the green water event, which resembled a plunging wave with air...

... Abstract Steady incoming flow past a circular cylinder has been a classical problem in fluid mechanics owing to its extensive practical applications in e.g. offshore engineering. In this study, large-eddy simulations are performed for flow past a circular cylinder at the Reynolds number (Re...

... Abstract This paper presents the experimental investigation of vortex-induced vibrations (VIV) of a flexibly mounted circular cylinder in combined current and wave flows. The same experimental setup has previously been used in our previous study (OMAE2020-18161) on VIV in regular waves...

... Abstract This paper presents new laboratory experiments of two-degree-of-freedom vortex-induced vibration of a flexibly mounted vertical circular cylinder in regular waves. A new experimental model has been developed and tested in the Wind, Wave & Current Tank at Newcastle University...

... Abstract This article presents numerical results of flow-induced rotary oscillation of a circular cylinder with rigid splitter plate in steady flow. Different from the previous examinations with freely rotatable assembly which mainly considered linear restoring force, the rotary oscillation...

... and Technology, Trondheim, Norway dag.myrhaug@ntnu.no ABSTRACT Three­dimensional (3D) modeling of the flow around a circular cylinder in a steady, uniform current subjected to low and intermediate Reynolds numbers (Re) is considered. Large eddy simulations (LES) are used to simulate the flow due to their ability...

... Experiments have been carried out on two-dimensional devices fitted to a rigid length of circular cylinder to investigate the efficiency of pivoting control plates as VIV suppressors. Measurements are presented for a circular cylinder with low mass and damping which is free to respond...
