摘要 对雷诺数Re=200的圆柱在均匀来流中横向受迫振荡的问题进行数值模拟分析。通过改变运动圆柱的振荡频率和振幅,分析圆柱所受作用力及圆柱尾流泻涡结构的变化特性,振荡圆柱在非锁定状态和锁定状态下作用力曲线和圆柱尾流泻涡结构的变化情况,以及不同圆柱振荡频率和振幅情况下单个振荡周期内圆柱尾流泻涡结构模式之间的转换特征。 The numerical investigation of cylinder transversely forced oscillation in uniform flows with low Reynolds number Re = 200 is presented. The analysis is focused on the hydrodynamic forces acting on the cylinder, as well as the structures and module change of the shedding vortex in the wake of the cylinder, especially in the cases of lock-in and unlock-in state.
