Flow-induced vibration analysis of nuclear fuel rods using equivalent fuel element model

•The EQ rod model simplifies the complex geometry of fuel rods in FSI problems.•The technique reduces the computational costs in FIV problems.•The method overcomes divergence problems for the structural large deformation. This research investigates the Flow-Induced Vibration (FIV) of a fuel rod with...
