“…The high amplitudes happening in the upper branch at 5 < * < 7 are not very well captured with the numerical method implemented in this study which seems to be the major deficiency in the current approach. However; capturing the high amplitudes in the upper branch troubled the researchers working in this field for some time (Kinaci, 2016) and except a few exceptional studies (Wanderley et al, 2008;Wu et al, 2014) that partially capture the upper branch for some case studies, there is not a significant progress. The transition from the upper branch to lower branch is intermittent in Khalak and Williamson's experiments but this transition is smoother computationally and results in a linear decrease in the amplitudes.…”

Vortex induced vibrations (VIV) are highly nonlinear due to three different frequencies involved in the process; fluid force frequency, vortex shedding frequency and oscillation frequency. It is computationally complex to solve such a chaotic fluid flow but recent progress in numerical algorithms, turbulence models and computer capabilities have made it easier to approach the problem with a nonlinear approach. These developments have paved the way to approach the problem with the simple equation of motion of Newton's law and when coupled with URANS, which is a commonly used method in solving problems related to fluid flow, the highly nonlinear problem of vortex induced vibrations become solvable. The existing literature computationally can only handle flows for > 10,000 − 12,000 but the numerical methodology adopted in this study furthers this limitation. The numerical algorithm is first tried for a stationary cylinder and the boundary layer separation is investigated for higher . The generated results are found to be satisfactory to proceed solving for VIV at high . The solution strategy is tested in a wide range of Reynolds number with different springs and damping coefficients. Satisfactory agreement is found with the experiments for a cylinder in VIV. The shortcomings of the computational work and why these limitations arise are tried to be explained using the experimental results and the existing mathematical models.

“…Although the three-dimensionality cannot be captured by two-dimensional (2-D) models, the 2-D models based on Reynolds-Averaged-Navier-Stokes (RANS) equations have been demonstrated to provide good prediction of VIV and also the vortex shedding modes (e.g. Anagnostopoulos (1994); Guilmineau and Queutey (2004); Wanderley et al (2008)). Since a 2-D simulation consumes much less computational time than a 3-D model, systematic parametric study can be carried out at affordable computational time.…”

“…The present work is a contribution to the numerical solution of the viscous flow around ship-like bodies. In the present work, the slightly compressible Navier-Stokes equations (Wanderley et al [15]) are solved through the conservative upwind TVD scheme of Roe [8] and Sweby [11]. This finite difference method is second order accurate in space and time.…”
