The objective of this paper is to investigate the reliability of the mathematical model used for
estimating the U-Oscillating Water Column (U-OWC) response in the time domain. This …

In technical applications involving transient fluid flows in pipes, the convective terms of the
corresponding governing equations are generally negligible. Typically, under this condition …

Modeling an unsteady flow is an important problem in pressurized pipeline systems.
Depending on the dimensions and properties of the fluid and pipeline material, the …

A compression wave is generated due to a piston effect as a high-speed train enters a
railway tunnel. The compression wave propagates ahead of the train at local speed of …

Transient events are frequent in water distribution systems. However, until now, most of the
applications based on transient analyses are merely theoretical. Additionally, their …

Although derived from the principles of conservation of mass and momentum, the water-
hammer equations integrating dynamic friction are almost never expressed in conservative …

This paper details an efficient procedure to extract and analyze the pipe system
characteristics from the pressure and stress waves generated during the first half-period of …

The main contribution of the paper is to incorporate pipe-wall viscoelastic and unsteady
friction in the derivation of the water-hammer solutions of non-conservative hyperbolic …

In this study, the fluid hammer of viscoelastic flow in pipes is studied numerically. Here, the
Oldroyd-B model is used as the constitutive equation. This model is suitable for dilute …

In this paper, the occurrence of water hammer phenomenon is examined in a situation that
instead of water, an upper-convected-Maxwell fluid flows in a pipe system. This …
