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

This paper presents an intrinsic approach to estimate air entrainment rates due to intake
vortices based on large-scale laboratory measurements. Quasi-continuous measurements …

When pipelines are rapidly filled, dynamic and sometimes dramatic air–water interactions
often occur. These air–water interactions, along with their associated pressure and …

Objective: Today, Internet of Things (IoT) technology has a significant impact on overcoming
the challenges of water loss. The IoT also helps the reducing of these challenges. This study …

Transient (highly unsteady) air–water two-phase flows and spring-like geysers have been
one of the critical concerns in drainage pipeline systems, which may cause or exacerbate …

Emptying pipelines can be critical in many water distribution networks because
subatmospheric pressure troughs could cause considerable damage to the system due to …

An energy-dissipation model is developed to simulate rapid filling having an entrapped air
pocket within a vertical pipe. Both convective heat transfer and transient wall shear stresses …

Stormwater management model (SWMM) software has recently become a modeling tool for
the simulation of intermittent water supply systems. However, SWMM is not capable of …

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 …

The emptying procedure is a common operation that engineers have to face in pipelines.
This generates subatmospheric pressure caused by the expansion of air pockets, which can …
