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

With the development of urban areas, many municipalities are facing issues where the flow
velocity in their sewer systems is relatively high at various locations. This is because of …

There are few systematic studies to investigate the inherent reason behind the evolution law
of ejector performance, only some simple qualitative or roundabout analysis. In this paper, a …

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 …

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 rapid filling process in pressurized pipelines has been extensively studied using
mathematical models. On the other hand, the application of computational fluid dynamics …

Air expulsion from an end-of-pipe orifice in a rapidly filling horizontal pipe is investigated
experimentally and analytically in order to more completely characterize the system's …

The sizing of air valves during the air expulsion phase in rapid filling processes is crucial for
design purposes. Mathematical models have been developed to simulate the behaviour of …

ABSTRACT Modelling Intermittent Water Supply (IWS) presents challenges, as traditional
hydraulic methods based on EPANET are often inadequate due to their inability to simulate …

A filling operation generates continuous changes over the shape of an air–water interface,
which can be captured using a 3D CFD model. This research analyses the influence of …
