The effect of change in flowrate on power spectral density (PSD) of automotive radiator system for flow-induced vibration monitoring

The dynamic motion of internal fluid flow caused an interaction between the fluid's dynamic forces and a structure’s inner wall. This phenomenon will induce unstable vibration into the system and recently called flow-induced vibration. In this study, an experimental analysis was performed to id...
