| Numerical computations were conducted to investigate the vortex-induced oscillations of two adjacent circular cylinders, which are elastically supported by linear springs. The calculations were performed across a range of Reynolds numbers, spanning from 4200 to 42000. The cylinders were allowed to oscillate only in the transverse direction. The study aims to examine the influence of the spacing between two cylinders on their vibrations within the flow. The center-to-center spacing between the cylinders is varied between 1.2 and 4. The observed flow pattern exhibits different wake modes, accompanied by gap flow patterns. At a spacing ratio of 3, the response amplitude for both cylinders during lock-in is larger than that of a single cylinder. The characteristics of fluid forces, vortex patterns, output power as well as vibrational responses are extensively investigated in three different spacing configurations. |
