Abstract
The present paper describes preliminary results of numerical simulation of VIV
(vortex-induced-vibration) phenomenon around a pivoted circular cylinder
subject to steady flow. The present flow model is based upon the Navier-Stokes
equations with velocity-pressure formulation. The governing equations are
solved through the Spectral Element Method (SEM), which possesses the
property of high-order spatial accuracy as proposed by Karniadakis and Sherwin
in their book Spectral/hp Element Methods for CFD. The solution procedure and
characteristic aspects of the present modelling and numerical method are briefly
stated. The coupling method of the body motion with the flow problem is
restated from the viewpoint of the present problem. A series of numerical
estimation of VIV flow characteristics have been carried out for varying
parameters of the problem such as the reduced velocity and damping parameter,
etc.
Keywords: vortex-induced vibration, pivoted cylinder, spectral element method,
coupling of body motion with flow.
1 Introduction
In general, VIV (vortex-induced-vibration) problem is focused upon reduction
and suppression of VIV as noted in Blevins [2] and Sarpkaya [3]. As indicated
by Raghavan [4], and Bernitsas and Raghavan [5], however, it seems to be
probable to extract considerable energy from VIV phenomena. For example,
Professor Bernitsas has developed an energy extraction device known as
