Abstract
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.
期刊介绍：
The European Journal of Mechanics - B/Fluids publishes papers in all fields of fluid mechanics. Although investigations in well-established areas are within the scope of the journal, recent developments and innovative ideas are particularly welcome. Theoretical, computational and experimental papers are equally welcome. Mathematical methods, be they deterministic or stochastic, analytical or numerical, will be accepted provided they serve to clarify some identifiable problems in fluid mechanics, and provided the significance of results is explained. Similarly, experimental papers must add physical insight in to the understanding of fluid mechanics.
