摘要：

The tube bundle is the core component in the pressurized water reactor steam generator, which is prone to flow-induced vibration. In the mechanism of flow-induced vibration, vortex shedding and fluidelastic instability are typical strong fluid-structure interaction problems, which cannot be solved by decoupling the structural field and flow field. In order to better carry out the mechanical design of tube bundle in steam generator, the present work completed the fluid-structure interaction dynamic modeling of two flow-induced vibration mechanisms, vortex shedding and fluidelastic instability, using data-driven method. The prediction results were verified with existing experimental data, and they were in good agreement with the literature results. This method combines the advantages of the theoretical models and the consideration of actual structural dynamics characteristics in CFD calculations. It not only avoids the need for massive computing resources of three-dimensional fluid-structure interaction simulation in complex tube bundle, but also reduces the dependence of traditional theoretical models on experimental data, which is conducive to promoting application in engineering. © 2024 Atomic Energy Press.
