Emptying Operation of Water Supply Networks

Coronado-Hernández, Oscar Enrique; Fuertes-Miquel, Vicente S.; Angulo-Hernandez, Fredy N. (MDPI AG, 2018)

[EN] Recently, emptying processes have been studied in experimental facilities in pipelines, but there is a lack regarding applications in actual pipelines, which permits establishing the risk of collapse because of ...
Experimental and Numerical Analysis of a Water Emptying Pipeline Using Different Air Valves

Coronado-Hernández, Oscar Enrique; Vicente S. Fuertes-Miquel; Besharat, Mohsen; Ramos, Helena M. (MDPI, 2017-02)

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 produce the collapse of the system depending ...
Hydraulic modeling during filling and emptying processes in pressurized pipelines: a literature review

Fuertes-Miquel, Vicente S.; Coronado-Hernández, Oscar E.; Mora-Melia, Daniel; Iglesias Rey, Pedro Luís (Taylor & Francis, 2019-04-21)

[EN] Filling and emptying processes are common maneuvers while operating, controlling and managing water pipeline systems. Currently, these operations are executed following recommendations from technical manuals and pipe ...
Subatmospheric pressure in a water draining pipeline with an air pocket

Coronado-Hernández, Oscar Enrique; Fuertes-Miquel, Vicente S.; Besharat, Mohsen; Ramos, Helena M. (Taylor & Francis, 2018)

[EN] 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 behaviour. The emptying ...
Tracking of bubble trajectories in vertical pipes in bubbly flow regime by coupling lagrangian, eulerian and 3D random walks models: Validation with experimental data

Muñoz-Cobo González, José Luís; Chiva Vicent, Sergio; ESSA, M. A. Abdelaziz; Mendes, Santos (Multi-Science Publishing, 2012-09-01)

A set of air-water experiments has been performed under isothermal upward concurrent flow conditions, in a vertical column. The interfacial velocity, the bubble interfacial area and the void fraction distributions have ...
