AbstractElevated high points along a pipeline profile are the most common places where air vacuum valves (AVVs) are installed. This paper uses basic water hammer theory to semianalytically explore the effects of such AVVs. A simple frictionless reservoir-pipe-reservoir system with an exaggerated intermediate high point is considered with a sudden flow curtailment assumed upstream. Key design parameters such as the maximum air pocket volume, the duration of air pocket growth and collapse, and… 

Water Hammer and Column Separation due to Pump Shutdown

The phenomenon of water column separation (WCS) and subsequent air cavity collapse (ACC) can significantly increase the maximum pressure, with risk to damage or destroy the pipelines. In this paper,

Subatmospheric pressure in a water draining pipeline with an air pocket

ABSTRACT An air pocket’s behaviour inside of a pipeline during transient conditions is of great importance due to its effect on the safety of the hydraulic system and the complexity of modeling its

Hydraulic modeling during filling and emptying processes in pressurized pipelines: a literature review

ABSTRACT Filling and emptying processes are common maneuvers while operating, controlling and managing water pipeline systems. Currently, these operations are executed following recommendations from

The Crucial Importance of Air Valve Characterization to the Transient Response of Pipeline Systems

Air valves are often crucial components in an air management strategy for pressurized water conveyance systems. However, the reliability of characteristic curves of air valves found in product

Concerning Dynamic Effects in Pipe Systems with Two-Phase Flows: Pressure Surges, Cavitation, and Ventilation

The risks associated with unsteady two-phase flows in pressurized pipe systems must be considered both in system design and operation. To this end, this paper summarizes experimental tests and

The Challenge of Air Valves: A Selective Critical Literature Review

AbstractOne key alternative for removing, preventing, and effectively coping with the often vexing presence of air in water pipelines is the combination air-vacuum valve. Despite their often

Characterization of unsteady multiphase flows in stormwater management applications

Intense rain events create many issues in urban areas, including flooding, overflows in stormwater systems, sediment pollution, etc. In many circumstances, flows are unsteady and characterized by

Pressure surges in pipeline systems resulting from air releases

It is a common practice to locate air valves at high elevations along water transmission mains. Improper sizing of an air valve could lead to the rapid expulsion of air, which might result in

Transient Flow Caused by Air Expulsion through an Orifice

A pressurized water system may be subjected to high pressure surges because of the expulsion of a trapped air pocket through an orifice at the downstream end of the pipe. Results are presented of

Transient Flow in a Rapidly Filling Horizontal Pipe Containing Trapped Air

The pressure within a trapped air pocket in a rapidly filling horizontal pipe is investigated both experimentally and analytically. The downstream end of the pipe is either sealed to form a dead end

Experimental apparatus to test air trap valves

It is known that the presence of trapped air within water distribution pipes can lead to irregular operation or even damage to the distribution systems and their components. The presence of trapped
