Abstract
There are four popular items which may affect classical waterhammer results: unsteady friction (UF), column separation (CS), fluid-structure interaction (FSI) and viscoelasticity (VE), each of which has been investigated separately in numerous researches. In this study, waterhammer in a reservoir-pipe-valve system is simulated including - for the first time - all four items CS, FSI, UF and VE. The relative importance of each of the four items is assessed. Conclusions are drawn by looking at the numerical simulations corresponding to all possible combinations of the mentioned items.
Keywords: Column separation; Fluid transient; Fluid-structure interaction; Pipe vibration; Plastic pipe; Pressure surge; Unsteady friction; Viscoelasticity; Waterhammer
