Flow-induced vibration of twin-pipe model with varying mass and damping: A study using virtual physical framework
A hybrid virtual-physical experiment shows twin-pipe flow-induced vibration amplitude, frequency, and hydrodynamic forces depend strongly on mass ratio, with persistent vibration at m*=1.0 and a critical-mass interpretation near 1.1.
