This paper deals with the evolution of structural responses accompanying water hammer in quasi-rigid straight pipelines with emphasis on the effect of the support rigidity. The coupled discrete vapour cavity model (DVCM) is used to simulate axial str

Friction coupling affects water hammer evolution in pipelines according to the initial flow regime. Unsteady friction models are only validated with uncoupled formulation. On the other hand, coupled models such as four-equation model, provide more ac

The classical Discrete Vapour Cavity Model (DVCM) is widely used in standard water hammer software packages. Column separation in pipelines is usually predicted with this model. Nevertheless, its main weakness consists in the numerical instability an

Excessive piping vibrations are a major cause of machinery downtime, leaks, fatigue failure, high noise, fires, and explosions in hydraulic plants. High vibration levels usually occur when an acoustic natural frequency of the piping system is excited
