Energy dissipation structures, particularly stilling basins, are critical for defining the hydraulic
jump characteristics that are suitable. Appropriate sill geometry for abruptly expanding …

The aim of this paper is to investigate the complex nature of the transient energy dissipation
by using a computational fluid dynamics (CFD) model with a high spatial and temporal …

This work presents a quasi-two-dimensional unsteady friction model, with the longitudinal
coordinate considered as an independent variable and the radial coordinate embedded in …

High-concentration viscous paste has a large conveying resistance during transport in high-
pressure long-distance pipelines. When the pump reverses, the paste in the pipeline flows …

This work investigates a two dimensional numerical analysis of blood hammer through the
posterior cerebral artery. The non-Newtonian and usual Newtonian blood models are …

During water hammer wave propagation, pressure and velocity fields vary over time due to
transformations between strain and kinetic energies. In the literature, some energy …

The present study aims to bridge the gap between water hammer theory and non-Newtonian
fluid mechanics. To achieve this, a detailed numerical study is carried out to investigate the …

A two-dimensional model of distributed vaporous cavitation is developed for transient flow in
a low-density polyethylene pipeline. In this model, the governing equations of transient flow …

Quasi-two-dimensional (quasi-2D) friction models have been widely investigated in transient
pipe flows. In the case of viscoelastic pipes, however, the effect of different values of the …

A problem with 1-D water hammer modelling is in the application of accurate unsteady
friction. Moreover, investigating the time response of fluid dynamics and unsteady …
