WebApr 4, 2024 · 4 Concluding Remarks. The flow-induced dynamics of a chord-wise flexible filament, fixed at its leading edge, in a viscous fluctuating inflow has been simulated using a strongly coupled FSI solver at a low Reynolds number. The periodically fluctuating inflow is generated as the wake of a rigid stationary cylinder situated upstream of the filament.
