The validity of various methods of modelling unsteady flows - namely quasi-steady, rigid-column (with and without friction) and water-hammer (with and without fluid-structure interaction (FSI)) is examined at various time scales of excitation. One aim is to find the time scales for which ID-FSI is of importance in forced oscillating pipe flow. Illustrative examples are given for starting and oscillating laminar flows in a single pipe. © BHR Group 2008.
