Excitation and Damping Fluid Forces on a Cylinder Undergoing Vortex-Induced Vibration

Vortex-Induced Vibration Characteristics of an Elastic Circular Cylinder

A numerical simulation of vortex-induced vibration of a 2-dimensional elastic circular cylinder with two degree of freedom under the uniform flow is calculated when Reynolds is 200. 2-dimensional incompressible Navier-Stokes equations are solved with the space-time finite element method, the equation of the cylinder motion is solved with the new explicit integral method and the mesh renew is ac...

Robot Vibration Control Using Inertial Damping Forces

a numerical model of vortex-induced vibration on marine risers

the steger and warming flux vector splitting implicit scheme is used to numerically solve two dimensional reynolds averaged navier–stokes (rans) equations governing the vortex induced vibration of a flexible riser laterally supported by a spring and a damper. the k–ε model is used as turbulence model to simulate the turbulent flow in the wake of the riser. to update the new position of the rise...

Two- and Three-Dimensional Simulations of Vortex-Induced Vibration of a Circular Cylinder

Numerical simulations of the interaction between a circular cylinder and its wake during both forced and free, vortex-induced, oscillation have been performed using a spectral element method in which the computational mesh was fixed to the cylinder and the Navier-Stokes equations solved in this accelerating reference frame. Thus far, work has focussed on cross flow, rather than in-line oscillat...

Vortex Dynamics on a Cylinder

Spatially periodic rows of point vortices in a 2-dimensional ideal fluid have long attracted the attention of fluid dynamicists, one of the earliest and the most popular instances being Kármán’s vortex street [6], [15, photos 94–98]. The general problem is as follows: analyse the motion of an infinite configuration consisting of vortices z1, . . . , zN ∈ C with vorticities Γ1, . . . ,ΓN ∈ R tog...
