## Numerical Simulation of Fluid-Structure Interaction for Tube Bundles

• 摘要: 为了研究反应堆结构中的诸如燃料棒、蒸汽发生器和其它换热器传热管束等的流体-结构交互作用问题，利用有限体积法离散大涡模拟(large eddy simulation, LES)的流体控制方程，用有限元方法求解结构动力学方程，并结合动网格技术，建立三维流体诱发振动的数值模型，模拟直管束中流体的流动及结构振动，实现计算结构动力学(computational structure dynamics, CSD)与计算流体力学(computational fluid dynamics, CFD)之间的联合仿真．首先，基于流固耦合方法对单管的流致振动特性进行了详细分析，得到了其动力学响应与流场特性；其次基于建立的传热管束流致振动计算模型，研究了两并列管、两串列管以及3×3正方形排列管束的流致振动行为．
