“…Morse and Williamson [3] identifed a new vortex-shedding mode "2P 0 " through visualisation techniques. Lee and Lee [4] used numerical simulations to determine the Reynolds number Re = 200, diferent damping parameters S g S g � 8π2S 2 t aM * , where S t � f s D/U ∞ is the Strouhal number and M * � m/ρD 2 is the mass ratio), and the mass ratio of the cylinder when both inline and cross-fow motions are allowed to occur. Prasanth and Mittal [5] investigated numerically the vortex vibration of a cylinder with a mass ratio M * of 10.0 at low Reynolds number (60 < Re < 200) by means of a fnite element method and found that the response of the crossfow displacement can reach 0.6D.…”

A comprehensive 2D numerical model was conscientiously developed to investigate the vortex-induced vibration phenomena in a cylindrical structure with rounded corners. The Navier-Stokes equation was adeptly solved under the specific condition of a Reynolds number (Re) of 150. The investigation reveals intricate details of the phenomena. The study aimed to systematically analyze the interaction between drag and lift force coefficients, cylinder vibration amplitude, and the patterns of vortex shedding modes under various conditions. This study systematically altered the radius of the cylinder’s rounded corners to evaluate their effects on both structural and hydrodynamic responses. This variation was crucial in comprehending how slight alterations in the cylinder’s geometry impact significant changes in the flow dynamics and correlated vibration behavior. The model’s numerical results revealed the significant impact of the curved edge ratio on both the hydrodynamic forces acting on the cylinder and its vibration response. The variation in edge curvature resulted in changes in drag and lift coefficients, leading to a significant impact on the amplitude of vibration. This elucidates the crucial role of geometric design in controlling and optimizing the structural behavior of cylindrical structures under fluid flow conditions.

“…Morse and Williamson 3 found a new vortex shedding mode 2P 0 and certified 2P 0 mode formed only in the transition reduced velocity between initial branch and lower branch. Minhyung Lee and Sung-Yeoul Lee 4 investigated problem of VIV by numerical simulation under Re = 200. Different damping parameters, Sg ( Sg = 8 π 2 St 2 aM *, where St = f s D / U ∞ is Strouhal number, D is diameter of cylinder, f s is nature frequency) and M * ( M * = m / ρD 2 is mass ratio, where m is structure mass and ρ is density of fluid), are considered.…”

Vortex-induced vibration of two tandem circular cylinders with different diameters under low Reynolds number (Re = 200) is investigated numerically by solving the uncompressible two-dimensional Navier–Stokes equations. The arbitrary Lagrange–Euler method is used to simulate the movement of mesh. Effects of diameters and gap ratios are considered. Numerical results show that diameter ratios and gap ratios have little effect on maximum vibration amplitude. Four different vortex shedding modes are detected in this study.
