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 …

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

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 …

Air valves operate as protection devices in pipelines during drainage processes in order to
mitigate vacuum pressures and control the transient flows. Currently, different authors have …

Two-and three-dimensional analyses of transient flows considering the air–water interaction
have been a challenge for researchers due to the complexity in the numerical resolution of …

In hydraulic engineering, some researchers have developed different mathematical and
