Effects of valve opening on direct water hammer pressure characteristics in PMMA pipelines

Xiaoying Zhang et al.

Summary: In recent years, the application of viscoelastic pipelines in water supply engineering has become increasingly common. The viscoelasticity of the pipe wall in these pipelines attenuates the pressure wave as it propagates. The relationship between stress and strain in viscoelastic materials differs from that of elastic materials. This study investigates the generation of direct water hammer from rapidly closing valves with different initial opening degrees using transient elastic flow theory, taking into account both instantaneous and delayed deformation components. Experimental and numerical simulation results demonstrate the effect of valve initial opening degree on the direct water hammer pressure in viscoelastic pipelines.

Pipelines vibration analysis and control based on clamps' locations optimization of multi-pump

Xin Li et al.

Summary: This paper proposes a method of optimizing the clamps' locations for the vibration analysis and control of a multi-pump system. By calculating the system impedance and defining the objective function, the clamps' locations are altered to minimize the system impedance at different vibration frequencies. The Chaotic Swarm Particle Optimization algorithm is then applied to find the optimal clamps' locations.

Fluid-Structure Interaction in a Pipeline Embedded in Concrete During Water Hammer

Yu Chen et al.

Summary: This research focuses on the pipe vibration induced by water hammer and the fluid-structure interaction (FSI) that arises as a result. A six-equation model is developed to describe the vibration behavior of a pipeline embedded in concrete, considering Poisson coupling and junction coupling. An iterative approach is proposed to solve this model, and the results are validated through experiments and classical water-hammer theory. Furthermore, the dynamic FSI responses to water hammer are studied, and the effects of different parameters of concrete on hydraulic pressure, pipe wall stress, and axial motion are discussed.

Numerical modeling of water hammer in long water transmission pipeline

Mohammad Hossein Arefi et al.

Summary: This study modeled a water transmission pipeline under steady conditions and examined the transient flow caused by pump failure, finding that negative pressure phase may lead to water column separation and cavitation problems. It suggests that installing equipment like water flow feed and hydropneumatic tanks in the right places can significantly reduce pipeline risk.

An Overview of the Numerical Approaches to Water Hammer Modelling: The Ongoing Quest for Practical and Accurate Numerical Approaches

Susovan Pal et al.

Summary: This paper summarizes recent developments in key numerical approaches to water hammer modeling, focusing on the use of finite volume methods for accurate and efficient transient modeling. The Godunov scheme, first advanced in the FVM, is shown to be superior to the MOC in accuracy and computational speed. Further advancements in FVM schemes continue to improve the speed and accuracy of transient modeling in specific applications such as fault detection.
