Abstract: This paper highlights the importance of considering Fluid-Structure Interaction (FSI) in unsteady-state laboratory tests. Above-ground pipelines, in fact, if not perfectly constrained, can move during the generation of Water Hammer (WH). To study this, a one-dimensional mathematical model solved with the Method Of Characteristics (MOC) is used. The aim is to simulate the axial movement of a simple system tank - cast iron pipe - end valve, taking into account the combined effect of both the WH and the FSI phenomenon.
