摘要

我们进行了数值计算，以研究由线性弹簧弹性支撑的两个相邻圆柱体的涡流诱导振荡。计算在 4200 到 42000 的雷诺数范围内进行。圆柱体只允许在横向振荡。研究旨在考察两个圆柱体之间的间距对其在流动中振动的影响。圆柱体的中心到中心间距在 1.2 和 4 之间变化。观察到的流动模式表现出不同的唤醒模式，并伴有间隙流动模式。当间距比为 3 时，锁定期间两个圆柱体的响应振幅大于单个圆柱体的响应振幅。对三种不同间距配置下的流体力、涡流模式、输出功率和振动响应特性进行了广泛研究。

Computational investigation of vortex-induced oscillation of two side-by-side cylinders at high Reynolds numbers

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.
