Hydrodynamic coefficients for inclined cylinders

Ocean Engineering, 1998
Abstract The wave induced dynamic pressures around a circular cylinder of diameter 0.2 m due to regular waves were measured in a wave flume in a water depth of 1 m and in a wave basin in a water depth of 3 m. The experimental investigations were carried out with the cylinder inclined along and against the direction of wave propagation.

Dynamic response and hydrodynamic coefficients of a cylinder oscillating in crossflow with an upstream wake interference

Ocean Engineering, 2020
Flow-induced vibrations (FIV) of the cylinder with an upstream wake interference is rather different and more complex comparing with vortex-induced vibrations (VIV) of an isolated cylinder in the uniform flow, due to the wake interference mechanism ...

Hydrodynamic Coefficients for Risers With Strakes

21st International Conference on Offshore Mechanics and Arctic Engineering, Volume 1, 2002
Drag and inertia coefficients for offshore risers with strakes have been derived from model tests, and are reported in this paper. The coefficients correspond to flow conditions of forced oscillations with tow in the transverse direction, and without tow. For the forced oscillations the Keulegan-Carpenter (KC) range was 1 to 5.

Determining the Hydrodynamic Coefficients of a BOP

Volume 2: CFD and VIV, 2016
Blow-out preventers (BOPs) can be subjected to vortex induced vibration and also oscillating wave-induced loads from attached risers. Typically, the response of the BOP is estimated using heuristic codes and assumed hydrodynamic coefficients (added mass and drag) of the BOP and attached structures.

Hydrodynamic features of three equally spaced, long flexible cylinders undergoing flow-induced vibration

, 2020
Three equally spaced flexible cylinders are frequently applied in many engineering fields. The flow-induced vibration (FIV) hydrodynamic features of three such cylinders are not the same as those of an isolated single one and remain unknown.

Hydrodynamic Coefficients for an Extraterrestrial Submarine

Volume 7: Fluids Engineering, 2019
Abstract An autonomous submarine design was proposed as part of NASA’s NIAC program to explore the hydrocarbon seas of Titan, the Saturnian moon, and study its hydrological cycle. The submarine is to be capable of operating at both the surface and in a deeply-submerged mode.

Revisiting the Stokes-Einstein relation without a hydrodynamic diameter.

Journal of Chemical Physics, 2019
We present diffusion coefficient and shear viscosity data for the Lennard-Jones fluid along nine isochores above the critical density, each involving a temperature variation of roughly two orders of magnitude.

Hydrodynamic Coefficients for Straked Risers

Volume 6A: Pipeline and Riser Technology, 2014
A considerable challenge in deep water field developments is the possibility of Vortex Induced Vibrations (VIV) of flexible risers due to presence of high currents. The most common remedy is the use of VIV suppression devices such as helical strakes. The background for this study is the lack of guidelines for estimation of hydrodynamic ...

Experimental determination of the hydrodynamic coefficients of an underwater manipulator

Journal of Robotic Systems, 1999
A single degree-of-freedom (DOF) manipulator arm with a rectangular cross section is built to investigate the hydrodynamic effects, including drag force, added mass, and the moments induced by these forces. The drag–velocity relationships (linear and angular) are experimentally established and the drag force/moment coefficients are deduced.

Hydrodynamic friction coefficients of coated spherical particles

The Journal of Chemical Physics, 2009
The complete set of hydrodynamic friction coefficients for a spherical particle coated with a porous layer and immersed in a viscous fluid is evaluated in analytic form. The coefficients allow the calculation of the flow disturbance caused by the coated particle for any incident flow which satisfies the creeping flow equations.
