Abstract
A numerical method is presented in this paper which may be applied to mass oscillations as well as to the water hammer equations. The method is based on a combination between an implicit finite difference method (IFD) and the method of characteristics (MOC). The MOC/IFD method is used to investigate the instationary behaviour of pipeline systems in the transition region between inertially-governed processes and the spreading of pressure surges. A comparison between the results obtained from the rigid water column model (RWCM) and the MOC is also presented.
