Numerical investigations on flow-induced vibration characteristics of wire-wrapped fuel rod
S Qin, Q Ren, H Liu, D Chen, F Zhu, S Huang… - Progress in Nuclear …, 2022 - Elsevier
For the wire-wrapped fuel assembly in nuclear reactor, the high-speed scouring of coolant
combined with the transverse flow caused by wrapped wire can lead to the vibration of fuel
assembly, which in turn induce fretting wear and endanger the integrity of cladding. In this
paper, computational fluid dynamics (CFD) method is used to simulate and analyze the flow
induced vibration of a single wire-wrapped fuel rod at different flow velocities (2.5–6 m/s),
the flow field parameters and solid vibration response characteristics are obtained. Through …
