Transient events are frequent in water distribution systems. However, until now, most of the applications based on transient analyses are merely theoretical. Additionally, their implementation to real engineering problems is limited due to several physical phenomena accompanying transient waves, which are not accounted for in the classic approach, such as unsteady friction. This study investigates different unsteady friction models’ performance in terms of accuracy, efficiency, and reliability to determine the most-suited engineering practice. As a result of this comparison, Vítkovský’s unsteady friction model was found to be the best fit and was then implemented in WANDA commercial software. The implementation was verified with experimental data based on a reservoir–pipe–valve system. The model proved excellent performance; however, it was noticed that it fell short in simulating plastic pipes, where viscoelastic effects dominate. The upgraded software was then tested on different hydraulic networks with varying pipe materials and configurations. The model provided significant improvement to water hammer simulations with respect to wave shape, damping, and timing.

“…However, commercial software usually use a (quasi)steady friction assumption that notably affects the simulations' quality [11]. Unsteady friction is among other dynamic phenomena that significantly affect transient behavior [12]. In contrast with steady friction, unsteady friction is dominant in the transient event's later history [13].…”

“…Mono-dimensional elements make possible the solution of simple numerical problems for a complex phenomena, avoiding large Fluid Structure Simulations (FSI) with difficult boundary conditions and numerical issues. In [18], an extensive literature review on the state-of-the-art numerical models in 1D, the Fluid-Structure Interaction is proposed. In the presented paper, two systems are studied: a double fixed pipe and a hinged pipe to its boundary.…”

Annulus pipe conveying fluids have many practical applications, such as hydraulic control lines and aircraft fuel lines. In some applications, these tubes are exposed to high speeds. Normally, this leads to a vibration effect which may be of a catastrophic nature. The phenomenon is not only driven by the centrifugal forces, but an important role is played also by the Coriolis forces. Many theoretical approaches exist for a simple configuration or a complex three-dimensional configuration. Finite element models are tested. This paper provides a numerical technique for solving the dynamics of annulus pipe conveying fluid by means of the mono-dimensional Finite Element Method (FEM). In particular, this paper presents a numerical solution to the equations governing a fluid conveying pipeline segment, where a Coriolis force effect is taken into consideration both for fix and hinge constraint.

“…Theoretically, partial differential equations (Wang and Eat Tan, 1997;Tijsseling, 2003;Yang et al, 2004) are used to describe the pipe flow in which friction (Zarzycki et al, 2011), Poisson's (Wiggert and Tijsseling, 2001) and water hammer effects (Henclik, 2015) are generally included. Ferras et al (2018) investigated the fluid-structure interaction in a pressurized fluid-filled pipe. Yang et al (2017) developed a model resolving the pressure response of a pneumatic brake circuit with the effect of a transmission pipe.…”

A severe oscillation, accompanied with an abnormal "click" sound, of a fuel feeding pipe system during valve closing, when the feeding flowrate reaches a certain value, is observed experimentally. A fluctuation model in which stiffness and damping coefficients of the vibration system are time varying is proposed. Each coefficient is composed of two parts, one of which is constant and the other is time varying. Based on this model, simulation transients of the vibration displacement, velocity and pressure in the pipe are presented. Simulations of the pressure transients are compared with experimental data detected by pressure transducer, which shows that both have fluctuations in the transient process at a large flowrate.
