Water conveyance systems are notorious for incurring considerable energy expenditures,
either as losses of gravitational potential energy or as increased electricity consumption …

Water temperature affects the peak pressure damping of transient flows in viscoelastic pipes.
Owing to the viscoelastic properties of pipes, the accuracy of peak pressure damping …

Omission of frequency-dependent hydraulic resistance (skin friction) during modelling of the
water hammer phenomenon is unacceptable. This resistance plays a major role when the …

This paper experimentally and numerically investigates the water hammer phenomenon in
serially connected steel and HDPE pipes with different diameters. The aim of the laboratory …

The transient process is the key for the design, operation and maintenance of the pipeline
network system of the water supply project. This paper aims to study and develop a new type …

Air valves are protective devices often used in pressurised water pipelines, ideally admitting
air to limit sub-atmospheric pressures and controlling the release of entrapped air. This work …

Transient flow in pipe is a much debated topic in the field of hydrodynamics. The water
hammer effect caused by instantaneous valve closing is an important branch of transient …

The purpose of this research is to solve the complex long-distance and high-lift water supply
engineering accident water hammer protection problem. Taking the Zhaojinzhuang water …

Starting up water installations is typically a task that falls within the purview of water utility
companies. These operations involve the presence of two separate fluids (water and air) that …

ABSTRACT A stepwise method is one of the efficient approaches in the calibration of
transient flow in viscoelastic pipes. However, there is the lack of comprehensive research on …
