Numerical simulation of vortex-induced vibration of a pivoted cylinder using the Spectral element method

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. ？ 2012 WIT Press.
