Simulation of high Reynolds number flow past Arrays of circular cylinders undergoing vortex-induced vibrations Conference Paper uri icon

abstract

  • We present numerical simulation results for two-dimensional incompressible flow past freely-vibrating cylinders in tandem, side-by-side, and in square array arrangements. The case of fixed cylinders is also considered for the purposes of validation. We consider a center-to-center spacing of 5.5 cylinder diameters and Reynolds numbers up to transitional flow conditions. Of interest is the response to vortex induced vibrations (VIV) for low mass ratio and damping. The discretization procedure is based on local analytic solutions of the linearized momentum equations in conjunction with a discrete projection method to enforce the divergence-free constraint. Overset grid capabilities allow grid components attached to the circular cylinders to move in fixed background meshes. Copyright 2005 by The International Society of Offshore and Polar Engineers.
