Abstract
The validity of various methods of modelling unsteady flows – namely quasi-steady,
rigid-column (with and without friction) and water-hammer (with and without fluidstructure
interaction (FSI)) is examined at various time scales of excitation. One aim is
to find the time scales for which 1D-FSI is of importance in forced oscillating pipe
flow. Illustrative examples are given for starting and oscillating laminar flows in a
single pipe.
